Having problems with the brakes on my '99 DSE, changed the ball joints last week, noticed a snapped reluctor ring so i also put 2 new CV joints on it, also 2 new sensors as i destroyed the old ones taking them out. Sensors are pushed so they touch the rings and within yards of me driving off all the lights (ABS, TC) went out on the dash. The brakes are normal up to 30 MPH, anything over that and i have a rock hard pedal with reduced braking, i can also feel a slight pushback and hear a little creaking. If i stab at the pedal a bit harder it goes down and braking improves but theres more pumping. There are no ABS or TC warning lights when this is happening, anyone got any ideas?
