Another Brake Caliper renewal

[colb]

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.

Nice work! I've just had my two front ones replaced at 184k miles, I was convinced I had a buckled wheel, lots of vibration at times and then it went away, came back etc, 90% sure it was a sticking caliper - Thanks to the forum I discovered the wheel was a red herring.

What symptoms were you getting just out of interest?

First time around it was the drivers side calliper sticking, the piston was seized solid so wasn’t retracting when brake pressure was released hence hot wheel.
Latest visit was to clean passenger side but although not sticking had a fairly crusty piston and pad material breaking up. Best course of action taken and new calliper and new pads fitted. Discs ok for the summer but plans to renew from and rears winter time remains to be seen if rear callipers will be serviceable. Symptoms on this one was just a hot wheel but severe overheating could case disc warp and produce steering shake under breaking. Only way to solve that is a working calliper good pads and a new disc.
I always repair as an axle set.

Thanks, I can confirm it stopped the vibration and excessively hot wheel I was getting around 50mph+ too, was the sticky calliper. It was tricky as it was intermittent. New callipers, discs and pads on both sides.

I have a separate issue with the steering tramlining a bit at higher speeds but it looks like that was discussed last week on here on a separate thread: https://z4-forum.com/forum/viewtopic.php?t=148466
