Hi all, thanks for your replies. I think that there is a little misunderstanding. my rear brakes are not working at all. they are not locking up, the front ones are, the front of the car wants to stop but the rear wants to keep going. I have only a quarter of my brake pedal travel. Pedal almost goes to the floor and is a bit spongy. Looking at them today, will get back for more advice if it beats me. thanks again
