Zedshed Cymru had a return of one of our Group members cars today, previously changed a sticking Caliper on the front off side so return was to strip and clean the nearside one today. Stripped down revealed this one although not sticking was on its way to start sticking, rust build up on the piston head was quite significant. What was most alarming was that one of the pads friction material had delaminated from the metal pad and had started breaking up and cracking. Decision made to replace the Caliper and fit a new set of pads (axle set).
Ordered online through Halfords and collected within the hour. All the bits refitted and system bled, did get a brake pad warning light on start up so a quick disconnect and a spray with electrical contact cleaner in the plug and socket saw that warning light put out, so bad connection was the cause. Quick wash down and used some Jennychem rinse aid after a good shampoo with Wash and Wax shampoo. Rinse aid worked really well followed by a quick towel dry to avoid any water stains which on a black car can look really bad. Turned out nice and shiny.
Plans afoot to replaced all Discs and rear pads at the end of the year, but all good for some Summer motoring at the moment.
Post-mortem on the old Caliper revealed the head of the piston was very pitted and it was starting to make its way down the piston, inner seal was quite swollen and it took some force with the airline and WD40 to push it out. Good call to replace it at this time.
