Brakes went out (not working)

[Danny T]

I was riding in some very muddy wet conditions and my rear brakes were working great. When i got home i went riding around the block and when i push down on the rear brake it goes down very far (feels like no pressure) and the brake does not work. My brake pad has about 30 percent left, and my rotor is pretty beat up. But even when i had no brakes before you could feel the pressure in the pedal.

It kind of feels like the piston is not pushing out fully in the caliper.

Do i need to bleed the brakes? DO i do this while the whole assembly is still attached or take them apart then bleed?

I have never done this before so any tips are appreciated.

Thanks in advanced.

Whats the fluid level of the rear brake resivoir?

+1 good question. If you keep pushing brakes, does it eventually "pump up" If so bleed em and refill fluid. Bleeding doesn't require removing anything.

i am not home right now to check the fluid(stupid me should have thought of that) but it doesnt eventually pump up. It just feels like low pressure constantly.

no fluid, and/or blown line. Good Luck.

Could be mechanical, too? I doubt it, but possible.

hey guys, had my brother go out and check the fluid. it was pretty much empty he said. So question is when i refill it should i bleed em, or just fill it?
And does the fluid generally go empty over time, or only if there is a leak in the line(i have never seen any fluids on my garage floor?)

Thanks again!

I would bleed, in case any air got in the break line.

ok is the spot where i bleed from the item that looks like a zerk on the caliper. Do i just apply brakes, loosen it a bit, tighten, then release brakes?

Thanks again guys.

im bored at work wish i was home with my baby(my raptor)!

Correction it takes two normal, non-monkey armed people.
