started a new thread because it seems brake master cylinder wasnt the problem.

replaced brake master cylinder
brake booster
brand new driver side caliper
brand new rotors and pads
brand new drums

heres the deal the the brake pedal constantly feels like has air in the lines therefor it will not stop/slow down the car unless i slam the pedal.When i do slam the pedal the wheels lock up(front only).e-brake is still tight and works so i have back brakes but they do not lock up when i use the pedal like the fronts do.

anyone have any idea what the problem is,im taking it to mizer tomorrow because they installed the pads,rotors,drums etc etc

 

hell yeah id take it back. sounds like you either have a shit load of air in the system or a terrible fluid leak

 

If there is no visible leak, it is more likely that you have air in the system. Rebleed it. Make sure you do it properly starting from the farthest side to the nearest side.

 

i will search for leaks today,i havent seen one yet but maybe i was wrong.after we had all the shit put on it felt mushy and we took it back to mizer they bleed it and said it was either the brake master cylinder or caliper,REPLACED BOTH.mizer just sucks

 

didnt see any leaks,im just going to bleed about 1 pound of brake fluid through the system,then pressure wash underneath the car and keep an eye for a leak,

 

combonation valve sounds like control front to rear pressure balance sounds like it was probably bled wrong and blocked off ports in the combo valve and you have no pressure going to the resar brakes look into the combo valve/ proportioning valve

 

did you bench bleed the master cyl. b4 putting it in?

 

yuppp

 

can air trapped in the brake lines build up enough pressure to crack the lines,im asking this because my two rear bleeder screw were cracked?advance auto said they had never seen anything like it.

 

Your bleedeer screws in the rear broke? How come you didn't see it last night..
