Dee2 Posted August 17, 2012 Share Posted August 17, 2012 '90 Loyale sedan FWD While trying to isolate a noise source from the front end, I noticed the front brake discs have some light surface rust on them as if there is no contact from the pads. The pads are probably around 60-70% so they are good. Last time the brakes were done, couple of years ago, the back brake pads were gone and the front were still at 70%. I suspect the calipers aren't doing their job. The car seems to brake ok, not fantastic, but ok. What is best way to test just the calipers ?

GeneralDisorder Posted August 18, 2012 Share Posted August 18, 2012 Frozen slide pins. GD Quote Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted August 18, 2012 Share Posted August 18, 2012 you'll have about a 1/16" inch ring of no-contact on the outer and inner diameters of the rotor... other than that, like GD said, frozen pins, OR air or grease is stuck in the slide pin shaft and is causing a buildup of pressure everytime you apply the brakes feeling like a stiff pedal...
