Porsche brakes, doesn’t your pads fit in the calliper any more?

Been reading a lot on this brilliant site lately, and it's probably time to give something back. ;-) Had to change rear rotors and pads on my RS2, and the callipers needed a proper job.

Time for calliper stripdown!!

The aluminium block under the guide plate has corroded, and the guide plate will be in the wrong position. The guide plate looks like it’s swelling, and your pads won’t slide as supposed to.

Solution: take off guide plate, and treat the aluminium block behind the plates with proper anti corrosion coating. Probably all the small torx heads holding the backing plate will be small ******s to get loose, but welding them out makes it easy.

Read several places it’s not recommended to split the calliper, but I can’t see why not. The job to clean and proper coat the block behind the backing plates will be a lot more easy when you split the calliper, and my callipers at least look and function fine after reinstall.

This is how mine looked, not nice.

Then use some Galvapro or other coating, after some serious cleaning and trimming. I topped this of with some heat resistant paint, to protect even more.

Then my camera went out of battery, but I can promise you everything looks fine now, and the pads can move free and easy. ;-)

This should probably allow the callipers to work properly for several years.

English is not my daily language, sow neglect my spelling errors… ;-)
