i have a serious prob with my 98 wagon brakes,anyone any ideas,whats happening is when slowing down to a halt the brake pedal pulses at last few seconds of braking ,and makes the sound of cogs slipping,also when driving at speeds of over 80mph and brake heavily car veers all over the road,and there is no brake unless reaplied,the pedal is firm no air in system,there is no abs light on the dash,just fitted 4 pots this morning checked the abs ring behind disk thats fine,any ideas.

 

jack the car up , hold the wheel top and bottom and shake it to so if there is any play , it sounds as though your wheel bearing could have gone , this will give you noises , and lose the brakes until you pump them

 

there is no play on any wheels.

 

worn pads, cracked/warped discs, old brake fluid, air in system.... could be any of this really mate.

 

As above plus: sticky or seized caliper pistons, mis-matching pad compounds front to rear (i.e performance front, stock rear affecting bias), worn shocks, sloppy suspension bushes, different tyres brands or wear across the same axle (or front to rear).

 

sounds like the abs working

 

cracked abs ring

 

defo an abs ring,i disconected a sensor no probs now but light on and obviosly no abs must be one of the rears cause fronts are ok,checked them while fitting 4 pots.
