ok when i push the break peddle down my friend can still move the back tires(car is on stands right now, i was low on fluid. even after adding more fluid the peddle seems really lose like there is no grip at all



any help?

 

you got to bleed the brakes. Probably all around.

 

when you engage the parking brake, can your friend still turn the rear tires?



if so, i'm gonna have to say your rear calipers are siezed.

 

the parking breaks stop the rear tires

 

Bleed them again.

 

yep, if the parking brake works theres probably air in the hydraulic system for the rears (assuming the fronts work great).





was there any work done recently on the car? new master cylinder perhaps? if you are bleeding brakes make sure you do them in the proper order.

 

and in case you don't know the order:



passenger rear

driver rear

passenger front

driver front
