Hi! I have a problem with my rear brake balance. The left rear wheel has less stopping power than the right rear wheel (I had the car tested and left rear wheel had 1.0KN of stopping power when the right rear wheel had 1.4KN which means a 40% difference). The front brakes are correctly balanced. All the brakes release correctly after using brakes and the hand brake is also correctly balanced. As such, I believe that the problem is caused by brake fluid pressure applied to rear brakes. Car details: Golf mk3 1996 1.9L TDI 81 kW with VNT turbo ABS brakes with drums in the rear (ABS system seems to be working ok and will activate under heavy braking) Some questions: Does this car have brake pressure regulator or does the ABS system take care of the brake balance? Where the pressure regulator is located if I have one? Can I somehow verify that it's broken short of replacing it in the first place? The car has old brake fluid in it (more than two years), could this be fixed by only changing the fluid? Anything else? What I should check next?
