Okay, after I get my car back from eric ( for all of you who know the story) The master cylinder was bad, It wouldn't hold pressure.

I bought a refurbished M/C from autozone yesterday, installed, and bled the brakes. they worked fine ALL yesterday, I drove all over town and they worked fine.

When I got in my car today, the car started fine, brakes worked fine. and i started driving, and slowly the brakes started grabbing harder and harder by themselves. Now the pedal feel rock solid when the car is off.

Bad master cylinder?

poison

When you put the M/C on, did you push the piston on the brake booster at all?

Filliam H. Muffman

..nope.

I just went downstairs, and loosened the front hard line on the MC, brake fluid shot out, and i heard the front calipers loosen up.

So it was my MC, but whats wrong with it?

poison

does the brake booster piston retract when you push on it?

seems odd.

did you bench bleed the master cylinder before installing it ?

..no i prefer to have 100% air in my master cylinder.


well anyways, in hopes that my master cylinder was still good, i pulled it off, cleaned it up, and put new brake fluid in. i didnt bleed the lines yet, and the car braked just fine for having air in the lines, i was bleed the lines today when my brakes locked up on me AGAIN. pedal was rock solid.

Try to be nicer to people that are helping you.

I just last week fixed this same problem on my car after having upgraded my brakes to gsr ones. At first I replaced both rear calipers since they where the ones locking up and that didnt help. It turned that the problem was that I was using an ABS brake booster and a non-abs brake booster. On ABS boosters the rod is longer than on non-abs. Make sure that the booster and mc combo you are using are either both abs or non-abs. I pretty sure that could be your problem.

SORRY SORRY, bad day. Don't get butthurt over sarcasm. its the interweb people.

When I said in my first post "bled the brakes" that included the master cylinder too, sorry i wasnt more clear.


anyways. its not the calipers because they loosen back up when i undo the banjo bolt. I think I might just replace the master cylinder, again. because that seems to be the trouble.

Does anyone know if a bad MC/BB combo could cause this?

calipers and lines usually hold pressure, not MC. Check your lines too.

But it is a autozone product, so anything is possible.
