[2001300exguy]

ok my rear brake pedal has no firmness at all when i push it down it will go down past the frame. i have plenty of fluid and when i loosen the bleeder on the rear brake fluid comes out but no air. any ideas

[vinson581]

are you sure your bleeding them correctly?

[2001300exguy]

nope, i loosend the bleeder valve a little and lightly presed the brakes and all that cam out was brake fluid

Does the fluid come out anywhere else, sounds like you have a blown seal somewhere. I just had to rebuild a buddies not long ago, just look for another fluid leak somewhere.

no leaks any where alse the fluid is still on the higher side

[duke416ex]

Just keep pumping it, if it is a leak then it will come out somewhere. Also, take the caliper apart if you can't find a leak and inspect the o rings around the cylinder to make sure they aren't blown. GL

Can you pump it up at all and get any resistance meaning do you have any rear brake action at all?

If so, pump it up 20-30 times if necessary and strap the brake pedal down as far as you can. Loosen the cap all the way off the reservoir and let it sit there. Go to bed.

Repeat the process in the morning and then go to work.

If you really want to have the firmness in your brakes back, do it one more time and then go to bed again.

By morning, your brakes will be perfect. If not, you got a problem in the brake system. Could be the caliper of the rear brake cylinder.

By the way, this is commonly referred to as Reverse Bleeding.


Also, you should never open the bleeder valve without pressure on the brake pedal. Also, do not let the brake pedal bottom out while the bleeder valve is open.
