Rear brake problem

[RedlineRacer]

Hey guys, remember me? Haven't posted on here in years. But, anyway, today I was changing my rear brakes pads, and everything was going smooth until the end. I change the pads, bled the brakes and tossed the wheel back on. Then I hopped in my car and pumped the brakes, and it wouldn't get stiff. So then I took off the wheels again and bled the lines once more. No difference. What could I have missed? Ive been beating my head over it for half an hour now. I thought maybe its the MC, but how could it have gone bad? It was working fine before the change. Any help would be appreciated.

Maybe a bubble crept up the line while you had it open. Try a gravity bleed and see what happens. If you were doing this job solo, I don't see how you could have properly bled them. The only way I know of to bleed solo is with a bleeder bottle or a brick and speed bleeders. I say gravity bleed all four and see what you get. BTW, did you check the calipers after you tried the brake, make sure one of the seals isn't leaking?

I'll give that a try, thanks.

If you were just changing the pads why did you bleed the brakes? Did you dissconect the caliper lines for any reason? If so did the MC empty out during this time?

Just a thought here...how did you push the pistons back in? With brute force or a c-clamp or did you rotate it back down?

Otherwise check for leaks and double check the install.

I screwed the pistons back in. I bled them cause alot of fluid came out and i wanted to make sure no air got it since the reservoir was low, but the MC never fully emptied out. And I never disconnected the lines. The driver side piston was really hard to screw in. I could only screw it in about half way.

How did fluid come out if you didnt disconnect the lines? Do you mean fluid came out of the MC when you pushed the pistons back in?

your driver side piston may fail pretty soon.

However, that (alone) shouldn't give you the described problem.

My one person brake bleed setup...

1 ltr wide mouth soda bottle (mtn dew)
A length of vac hose to fit on bleed nipple (preferably 18 to 24 inches long).
A metal coat hanger.

Drill a hole in the cap to fit the hose through. Make sure end of hose rests at bottom of bottle whith lid on. Fill bottle with aprox two inches of fluid.
Wrap one end of the coat hanger around the neck of the bottle, and fashion a hook to hang it with.

Proceedure...

Hang bottle from a suspension part close by the caliper. install hose end on bleeder valve. Open bleeder, let the hose twist up while you open the valve( the reason to have 18-24 inches of hose). Make sure your brake fluid resivoir is full. Pump break pedal 3-5 times(if your agile you can look under the car while pumping to see the bubbles in the bottle). Close bleeder valve WITHOUT removing hose. Move to the next brake location.

or.... speed bleeders from SPLparts
