Hey guys, sorry I have been gone so long, I am trying to finsih up the car and start heading to car shows! I have a question on the F body brakes.... I installed the calibers, new SS 5th brake lines that connect to the caliber, and the needed 12" rotor. Heres my question, when the car is off, the brakes tighten up just fine and the pedal holds, but when I start the car, I lose it in the pedal unless I reapedetly hit the pedal. I did bleed the brakes but with the car off. Any suggestions would be greatly appreciated! Yes I did check for leaks and everything is dry, so any help would be great! Thanks guys

 

well ive never done an f body brake swap, but i would check your master cylinder first, maybe it leaks under vacuum, its the only thing thats really different with the car on or off. just a thought!

 

My guess is that you have air in your line

 

Try rebleeding the brakes with car running.don't know if it'll help.you could have a bad brakebooster

 

Figured it out, She stops on a dime now :-)

 

Well what was the problem and fix?

 

haha a rookie mistake... i had the calipers on the wrong side, therefore making the bleeders on the bottom and making them impossible to bleed haha. My bad.

 

THanks for sharing!! I forgot about that piece of info but I HAVE read it before. Never hurts to share lessons learned.

 

i did the same thing when i put mine on...i felt like i was bleeding for hrs...lol

i felt really stupid once i figured it out...lol

 

lol Im glad Im not the only one!
