I am having some serious frustration with a simple brake job. I replaced my front and rear pads. I replaced my front rotors as well and just left the rears be. I used a c-clamp to decompress the calipers with the cap off. Did all that,then installed them,bled the hell out of the whole system 3 times. Cranked the e-brake numerous times to set the rears. Pedal is still extremely spongy and I can take it to the floor. I know I am not leaking any fluid and nothing I beleive is kinked or knotted up. I marked on the master cylinder a fill luine and pumped the breaks with the car running 50 times and no fluid loss at all. I have no clue what the hell the problem is. Please help....

 

did you start with the furthest brake line from the master cylinder?

how are you bleeding the system?

 

Yes I started with the farthest...I had a fellow coworker of mine help me while he was in the inside. We have done this to several cars in the past. There was no air in the lines whatsoever.

 

why did you bleed the brakes for a rotor swap and pads?? i wouldnt have bothered, i would rebleed them though. one more time just for ***** sake, might of got air in them

 

There was no reason for me to bleed them thats just it. It was like that before I bleed the **** out of them. I though bleeding them would fixed whatever is wrong with them..it makes no sense.

 

hmmmm

bad master cylinder??? dunno...

 

i dunno either man...something had to happen from me compressing the calipers but they are all working.

 

when i did my brakes they went back to the normal pedal feel after a couple of pumps.

damn, wish i could come help, but miles away.

good luck to yah brutha.

 

I have seen something as simple as doing a brake fluid flush take out the master cylinder
just weird how stuff like that works, as stated above i would try to bleed them more try going through as much brake fluid as possible, and sometimes the ABS motor and valves throw a fit.

 

Yeah thanks.....someone has to know....

I guess im just gonna flaush it again tomorrow...when I started it up after I installed them but before I flushed it...when the pedal felt like crap I was like....really...how does this happen

 

when u fulshed the system did u do with fresh brake fluid? (Sorry have to ask) Assuming you did, did you notice the old fluid change to the new fluid. (old fluid being dark colored, new being a light gold color).

 

Yes...but it was getting dark when I did the fronts...I cracked the rears about 10 times a piece and the fronts 10-15 times...Fluid was clean and new.

 

Did you blow a piston seal using a c clamp? You should be able to push them with just hand force.
