what could this be?


i can take it back to the guy but he wont be back in tow till monday and i need my car now its my DD


THANKS!

 

do you have brake fluid? my guess is that something is leaking.

 

yes i do. its more then half way full...

 

To rule out whether or not its leaking, add brake fluid, pump the pedal, and see if it leaks by looking on the ground and in your engine bay.

Have your tried pumping the brakes quickly to see if that would re pressurize your system?

 

yes i have pumped re peatedly with motor off and on...

havent seen any leaks from under the ar...

 

well if its not losing fluid, it could have some air in the lines, or the mechanic may have just F'd up your brakes and put them on wrong or something.

Did the mechanic by chance refer to the bolts on the brakes as "nubby things" lol

 

You may also have a bad brake master. Did he bleed the brake from the right rear to left front? This will insure that all the air is out of the system.
Thanks Robert

 

im pretty sure e did everything right... he has one it on all of my other cars before with no problems... i hope i dont have to pay more money to fix stuff lol...

 

I'd hazard a guess that you need to bench bleed your master.

did your mechanic spin the brakes pistons like make them tight by rotating them to the right( the rear ones ). it might be it. and how about the E-brake is it tight or loos?
