sredish Posted November 22, 2004 Report Share Posted November 22, 2004 About the only problem I've come across with this rebuild is the rear brakes. When I put the rear master cylinder on, there was no rear brake pressure at all. I figured I'd just bleed it, no biggie. So, a few days later, I bled the fronts, got the brakes going, and the went to the rear. Checked the fluid, good. Pulled out my vacuum, put it on and opened the bleeder. Brake fluid came out and I closed it. Then I went to bleed the lever by hand to get the tight feel back in it, and discovered that the lever still went all the way down, with a hint of feel at the very bottom. So, I tried bleeding by hand, and fluid came out like its supposed to, but could not get any feel in it, except for maybe a slight amount at the bottom. I have new brake pads, and they worked exceptionally when they were removed, so what the hell would cause them not to have any feel now? When I swapped the pads, I had to screw with the parking brake crap on the caliper. The parking brake is all removed except for the cover on the caliper, need to get a blockoff. Do I need to do something with that screw sticking out, or what the F is going on with them? Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 22, 2004 Report Share Posted November 22, 2004 You may still have air in it or the adjuster on the pedal is way off. Quote Link to comment Share on other sites More sharing options...
Toomey Banshee Posted November 22, 2004 Report Share Posted November 22, 2004 I had the same exact problem you had with my 94 2 weeks ago. I bled it etc. Try pulling off you caliper and hitting the rear brake lever until the piston on the caliper extends a pretty good distance, then press it back in and throw your caliper back on. Mine was gunked up I guess and when I did this it did the trick. Quote Link to comment Share on other sites More sharing options...
sredish Posted November 22, 2004 Author Report Share Posted November 22, 2004 I'll try pulling it off later. See what's going on in there. The adjuster is adjusted almost all the way out, so it can't be that. I could have some air in there I guess. Funny thing is, it was never opened up, so air shouldn't have ever gotten in there. Even so, i've bled the piss out of it, but i might drain all the fluid and replace it that way I know I've gone all the way through the hose with the fluid. Cool, thank for the ideas.

fixitrod Posted November 22, 2004 Report Share Posted November 22, 2004 If the wheel spins free (brakes not locked up) you wouldn't think the caliper would be stuck. If it were stuck shut the pedal should be hard to push. If the caliper is stuck with the brakes on, that would make since that the caliper was stuck causing your trouble. If you didn't crack it open but laid the system down in a way the air could make it to the lines or caliper you could still have air.

What you said there is probably what's happened, I'm so f'in thick sometimes, that's probably exactly what happened. I'm just gonna suck all the fluid out and then put all new in and eliminate any chance of trapped air. Thanks rod. Quote Link to comment Share on other sites More sharing options...

Thanks rod. 283869[/snapback] have you tried bleeding with a line on the bleeder going in a bottle with brake fluid in it. as your pumping the pedal you can see if any air is being pumped into the bottle, and it doesn't suck any air back because the hose is in the fluid. it works pretty good.

nater006 Posted November 23, 2004 Report Share Posted November 23, 2004 If you pump the tar outta it, does the pedal ever have the proper pressure? It sounds like its got air in it honestly. My 900RR front brakes spit brake fluid after a few pumps and bleeder bolt work, but still had air in them until they were just bled bled bled.
