Hi all,
I have a problem with the rear wheels skidding on my 1993 Fiat Uno Mk2 during an emergency stop! At least, it is more or less in a straight line rather than a complete loss of the back end (remaining rear tyre tread depth is 4mm on each side).
For some time now, I have noticed the rear brakes seem to be doing more of the work when applying the brakes, as shown by a temporary grinding noise when the car has been parked for as little as forty five minutes (not just the effect of an overnight build up of surface rust on the drums/shoes, which is to be expected at this time of year).
The old brake force regulator valve, which had seized, has been replaced and the rear shoes, cylinders and drums checked and replaced where necessary - in practice, only a new wheel cylinder or two). The skidding occurred both before and after fitting the new valve.
There are no signs that the (original) master cylinder has failed but perhaps it is starting to deteriorate and this is affecting the braking system?
The MOT testing station have offered to carry out a free brake test but not sure if this would show whether there is an imbalance between front and rear.
Any thoughts or advice would be appreciated.
Thanks,
Andy
