2001 Mule 550 Brakes

Recommended Posts

I'm embarrassed to say but I'm 58 years old and I never changed drum brakes before lol.  I have my mule that won't hold fluid. when I drive at top speed my brakes don't work.  I can let off the gas and stop ok so that is all that I have been doing.  There doesn't seem to be any leaks around maser cylinder.  I'm dreading that I will screw something up trying to change the brakes.  They have never been serviced. Only oil, fuel and air filter maintenance.  I looked on youtube but no videos of this model online.  I feel capable to do the job based on videos that I have seen with other drum changes.

 

My question here is what advice can you give me on this job?  What to look for and is it just a drum replacement kit that I need?  Do the cylinders come with it?  I'm assuming that's where they are leaking at although I see no evidence of leaking from the OUTSIDE of the hub.  My Kawasaki  dealer estimates 7-800 dollars to repair without having seen it.  I can't pay that but I'd like to try it myself.  What I DON'T want to have happen is that I pull the hubs and screw it all up and not be able to put it back together.

 

Thanks in advance. And don't laugh

I've been into my brakes a few times... 

The wheel cylinders are, from my dealer, $130 each. Check in the parts thread in this Kawasaki forum for other prices.

there are some chinese ones on amazon for about $50 I think.

once you get into the drum you can determine if the shoes need replaced. They might just need adjusted. Although brake fluid is kind of acidic and might eat away at the shoe material.

it's fairly simple. The rear ones have the E brake cable, so that's 1 extra thing to look after.

I would recommend buying a shop manual. I have one, I can post the page instructions here if you want me too.

I am new to this forum, and hoping I can find help with topics that I can’t find YouTube videos for.  I have a 2000 Mule 550 that I “got custody of” in my divorce.  It was purchased in 2004 from an individual, and we carried it to a Kawasaki shop for general service, fluid change, etc. at that time. Except for occasional oil change, and new tires,  nothing has been done to it since then!!!  It has been a great machine.  But recently, the right rear wheel locked up.  With the help of YouTube, my Daddy, and a good neighbor-I was able to pull the wheel and hub off (with a puller).   Cleaned the whole area, took the brakes off,(Making pictures after each step so I can hopefully put it back together), cleaned all the parts, and bought the service/repair manual.  I think the emergency brake cable was not releasing fully, and I need to adjust or replace it.  But my manual does not give any info on how to remove or adjust it.  Nor does it tell how to adjust the brakes when I put them back on. Does anyone know  where I can get this info?  If you would post pages from your shop manual, I would greatly appreciate it.  Thank you!

Never heard back from the OP? Seems he just left us hanging. 

To anyone trying to work on drum brakes for the first time. Always work on one side at a time. Leaving the other side intact, you'll have something to look at, and compare to, if you get confused about the assembly. And try to take a couple of pictures of the assembly before you start to take it apart.

Sorry, I guess it was us that left you hanging then. All drum brakes are pretty much the same. In your case, I'd pull the drums first. That can be a lot of trouble right there. Typically they've been on there for years and sometimes the drums are stuck on. And it can easily be the hardest part. So I'd pull the drums now, they should be easier to do when you get ready to do the work. 

So pull the drums, and find a YouTube instructional that looks like your own setup. It's not really critical. 

The parts you'll definitely need, are the brake shoes. Hopefully not, but possibly new drums. And if a wheel cylinder is leaking, youll need a new set. They are rebuildable, but replacement is best. Everything that gets replaced, gets replaced on both sides. Or you'll have uneven braking. This is important! Buy new brake fluid, plenty of brake cleaner. Be certain that it's non chlorinated. The chlorinated is toxic, and requires specialized PPE safety stuff.  And a couple of cardboard boxes to slide under the works to catch fluids.

I'd want all new hardware also. However that's not absolutely necessary. But it does make things easier. Because sometimes old springs cause uneven brake reset. That can cause wierd brake pedal feel, to uneven stopping, to a single wheel locking up when braking. But usually it isn't a problem, so if it's hard to find, or you're on a budget. You could probably skip that. 

You'll definitely want to replace the fluid though. That's a generic job also. Plenty of examples on YouTube. And doesn't absolutely have to be done at the same time. 

To get started, you'll need to pull the drums to expose the internals on both sides. Do one side at a time. Because on the reassembly, you WILL need to look at how it goes together. So leave one side unmolested, for reference. This can be critical so don't take it lightly. 

Hose everything down with non chlorinated brake cleaner.  I buy the cheap stuff at Walmart. Three cans should be plenty. Slide a cardboard underneath the assembly, and hose it down. Everything about this job is messy. Plenty of cardboard, and maybe something more protective, if you're trying to keep a pristine garage floor. Pre planning is important for this.

Take pictures as you remove each part. Because there's not many parts, but they're layered. Some parts go over, some under. And there's subtle differences between left, and right. So pay close attention, and take a few pictures. You'll know when you have it right, because of how it fits together. 

It's really not that hard, certainly a beginner could do it. Especially with the help of YouTube. But it could take most of the day, especially if you have problems. Or get side tracked. 

You might also need to source parts that you don't have. So don't do this in the driveway behind a car that you might need. You might have to order parts from the internet. So plan ahead on where you do this. It might be there awhile, or it might take a couple hours. Unless you go all new parts, and have everything you need, expect that it won't be a quick job. I've spent a half day doing cars, when the auto parts was just right there.  So prepare for a small project, and be happy if it just falls together. But understand that sometimes you'll find other problems too. Like bearings that are bad. Or leaking seals. 

Don't worry about getting in over your head. It really isn't that complicated. Although I might not have painted a rosey picture. I try not to over simplify. I want you to know what you're getting into. You'll be glad you saved the $800.00. But you'll understand why it costs so much. It takes lots of time. We'll be here if you have questions. It'll come straight to my email after this.

Welcome to the forum, and Good luck!

Sounds like a hot sweaty job right there. Especially at this time of year. But interesting at the same time. I spent some time in the swamp in Louisiana. Not at all what I was expecting. It was nice, in its own way.

 When you get back, and decide to tackle that project we'll be here. There's no timeline, it's all on your schedule. Stay safe.

      Hello everyone.
      Here I am showing our Green Scout electric all-terrain vehicle.
      All-terrain vehicle 6 wheeled, electric, side-turning. Rides, jumps, dances, swims, but does not fly. The drive is permanent (but you can turn off any wheel arbitrarily through the controller). The power of each wheel is 3 kW at its peak, the total power is 18 kW. Speed up to 60 km / h. Since the all-terrain vehicle is electric, it starts from a place quickly, drives silently (well, of course, the sound from tires and shock absorbers does not disappear).
      The idea of creating such an all-terrain vehicle came after the experience of operating the Argo all-terrain vehicle. The main disadvantages of the wheeled side-turning all-terrain vehicle are low ground clearance, lack of suspension. To get high ground clearance and suspension, there are two outputs on mini all-terrain vehicles - either electric drive or hydraulic. The hydraulics had to be excluded, since at temperatures below -30C it does not work, plus it always flows. As a result, we settled on an electric transmission. Each wheel is a motor-wheel. Naturally, the motor-wheels were being finalized to be able to be installed on an all-terrain vehicle and to be able to swim. The battery is iron-phosphate, all information on the battery, the charge is displayed on the smartphone. Control of the all-terrain vehicle through the on-board computer. Bicycle handlebar controls. Braking either with the sides through a turn of the steering wheel, or with the gas pedal of all wheels at once.

      I put a deposit on a mule sx xc about a month ago. The dealer said Kawasaki told them to tell the customer there would be a 4-12 week waiting period for delivery.  Do any of you have any insight what the actual delivery wait  time may be?  I live in Tennessee.

      I bought an axis 500 brand new, hauled it home and the light indicator for 4 wheel drive is not working.  Is there a something the store didnt tell me, or is it messed up right off the assembly line? Any thoughts or advice is greatly appreciated. Thank you!

      Hello all.  I'm new to the forum and have read all the posts I could find concerning the 550 Mule, so far no one with my problem. So, I'll give it a go and hopefully get an answer.
      I got this mule about three years ago, had to do some minor repairs, and it's been a great machine. Last fall, I noticed an oil leak coming from the left side around the crankcase cover.  I was able to slow the leak considerably, but it still leaked.  I never had the time to tear it down due to work. I retire in March of this year and decided to fix it with a new cover gasket. I ordered a new gasket and crankshaft seal and while waiting for them to arrive, I began the tear down and cleaning of the mating surfaces.  Got the seal and gasket installed and the cover back on and torqued. Decided to crank it up and let it idle a bit to check for any oil leaks before I put the converters back on. Fired right up, let it idle for about 10 minutes, no leaks. I'm happy at this point...
      Next day, installed the inside converter cover, new belt and converters, not the outside cover though. I wanted to see how the new belt was going to work out. I still had the rear end jacked up so it wouldn't move.  Guess what, it wouldn't start up. Cranked over like always, just wouldn't start... Now I'm bummed. So I start checking gas, spark and everything is good. Even tried a squirt of starting fluid, and it did fire a couple of times but no start. Now I'm even more bummed. Time for a break.
      Now I've worked on everything from small engines to tractors and have never had this problem.  After a little thought I decided to run a compression test. The repair manual lists 115 - 178 psi as the correct range, I had 30 psi!!!!! What in the world happened over night. I did spray a light oil into the cylinder and it came up to about 60 psi but that was all I could get. I checked the valve clearances, their good.
      Sorry for the long post, but I hope someone can point me in the right direction cause I really like this little machine.
      Thanks for your help,
      Roger

      Hey y'all, just finished replacing my rear right axle on my 99 mule 550. The old one teeth rounded out where the brake drum grabs it.  But now i can't get the drum to seat on the new axle far enough,  yes i put axles side by side,  identical,  i can reverse the drum and it slides right on the axle so i know it goes on fine.  It's a really bad design anyways with such a tiny line of teeth to rely on to drive the wheel.  Does anyone know if the new brake drums have deeper teeth to grab more of the axle?? Or any ideas why im having a hard time with this damn thing? 
    • By Travis
      The cables are sort of seized up on the emergency brake, they still work but i have to wiggle and pull on em to get them to release, i pulled the drum off but cant see a way to remove the cable. It is kind of dirty inside the drum where it was leaking so i need to run to the parts store and buy some parts cleaner so i can see everything better.
       The shop manual i have  does not cover parking brake cable removal, well.... it does kind of. it says "Remove parking brake cable at both ends" 🙄
       We'll see
       EDIT: ARRR! Looks like my rear axle seal is leaking, there is a small puddle on a machined step below the seal and it smells like Trans oil. felt around the wheel cylinder and it isn't coming from their.....  I guess my weekend is planned for me LOL
