Parking Brake Problems[200/1987] posted by Thomas Goot on

When I engage the parking brake and the car is in neutral (manual transmission), the car rolls slightly prior to stopping (I'd guess a max of a 1/4 of a wheel revolution). It is noticeable when parking on slopes. It feels like when you put an auto car in park and don't use the parking brake. The rolling action seems completely free and then there is a sudden stop, not as though the brakes are slowly slipping. Anybody know the cause of this??

A bit of rollback after taking your foot off the brake is quite normal, but I suspect you may have the beginnings of a problem.
There may be slop in your rear suspension allowing the rear axle to twist when the load is removed off the front wheels as you take your foot off the brake. Have the suspension bushings checked, especially the rear trailing arm bushings.
Secondly, your rear disc brakes may not be working properly. This can easily be caused by sticky brake calipers and less probably by a faulty or gummed up brake proportioning valve or an internally collapsed brake hose. If the rear suspension checks out okay then a full brake caliper inspection, test and bleeding is probably in order.
