Hey guys, I have had my raptor for about 7 months and it has never had back brakes.
Just getting to it now, the lever seems to go all the way down with no pressure, It has brake fluid, the caliper isn't seized, the pads are good, what do you guys think it could be?

Thanks

My 04 raptor back brakes are similar to what you describe. I think I will try to adjust them

Flush and fill with new brake fluid first. DOT #4 fluid. You could have air in the system. This should be done every two years anyway. The fluid picks up moisture that can cause rust in the system and brake fade. The only adjustment is the parking brake. Brake fluid is clear. When contaminated, it turns tan to brown to black. You want it clear.

If that does not work, then you may need to rebuild the master cylinder. It is not pressurizing the fluid.

Be sure your parking brake is adjusted or removed.

Borrow or rent a vacuum pump from your auto store and buy a can of "fresh" DOT4 brake fluid. Pull pressure thru the bleed screw on the caliper, keeping the reservoir full.

If the peddle firms up and the brakes work, you're done.

If the peddle firms up and the brakes don't work, your caliper is bad, and needs a rebuild.

If the peddle doesn't firm up, your master cylinder is bad, and needs a rebuild.
