2018 Massimo Buck 400 Brake Issues

[Michael Wood]

I have a 2018 Massimo Buck 400 with 278 miles. 
Having issues with my brakes. Took the buggy hunting and when I let my foot off the gas pedal it pulls without pressing on the brake. I looked and the pads on all 4 wheels are all toast. The E-Brake hasn’t been on since I have had it. I am guessing it may be a master cylinder issue because all 4 pads are gone. They all seem to have worn evenly that’s why I think the master cylinder. Just got the machine used from a older couple and they said it sat for some time in there pole barn. Possibly the brake lines? Calipers? I took one brake apart and when I depressed the caliper it didn’t stay. Any help is muck appreciated.

Probably the old couple drove around with the hand brake on.

Would that ruin the calipers or the whole system? I’m going to bleed the whole system and replace all the pads. It’s almost like there is no fluid release when the pedal isn’t being pressed. I only broke down one caliper. Also where can I find the parts? If you know. I looked on parts boss but that really sucks. Also I have to look up parts for a bennech cowboy 400.

I wish I could help you more. I have never touched the brakes on my Buck 400. I have a little experience with brakes, in general. I would try compressing the calipers with a c clamp. Fill the brake fluid and then carefully depress the pedal and see if it moves and if it leaks. Perhaps the calipers are ok.

I have never tried to order parts from Massimo, but they claim to have parts availablr.  https://massimomotor.lt.acemlnb.com/Prod/link-tracker?redirectUrl=aHR0cHMlM0ElMkYlMkZ3d3cubWFzc2ltb21vdG9yLmNvbSUyRlBBUlRT&sig=3NHTaUh8weXM7bUVJ4u2hWctgbfBHyS2mHs2yVQD9pH9&iat=1633437346&a=252445889&account=massimomotor%2Eactivehosted%2Ecom&email=vm%2FP6YlOt%2B%2BxDF21LTmNf735hO7C%2FF3J%2FgQB9Uu3XAY%3D&s=a1dcf2419babe4d32bd519d168baa028&i=94A118A13A1315

If it sat outside the disc's might have rusted badly and ate the pads when you began using it..maybe

Bleed and refill fluid. Take one caliper off at a time. Mark level in brake fluid reservoir, compress caliper and check fluid level. Should rise a little. Make sure you use the proper fluid for your vehicle. Use only what is specified. Master cylinder failure is rare but does happen. Your Massimo is a Hisun. Look on Amazon. Tons of stuff there. Also, make sure you lube your caliper pins and your pads to prevent squealing. There is a special lube for it, but I have used never seize as well. E-brake is pretty similar to the service brakes, just cable operated. You change the pads in a similar fashion. Check online for how you adjust it if you don’t have a manual
