AP Racing Rear Caliper bolt?

**cantfind1** · 13-04-2013, 11:57 PM

Anyone know of a supplier who would stock these.

Looking for the bolt on the rear caliper that holds the pads in. Mine has seized, typically, and before I try and get it out want to have a spare!

Was thinking a bit of heat my do the trick, but this will damage the paint, any other suggestions??

The bolt will be fine - its more likely to do damage to the thread in the calliper, as it is aluminium. When you do get it out, remember to put a small blob of copper slip on it.

If you use a hair drier, this should warm the alloy up enough to not damage the paint. You could also remove the calliper and lay it on its side on top of a bucket (so not to stretch the hose) and spray some Plus gas / WD40 in the threads, so that it can soak in?

AP will supply these, or go to Questmead for anything AP.

I replaced my anti-rattles and bolts last year due to the amount of action theyd seen, just wanted clean threads for the aluminium helicoils to stop them cross threading

The problem is caused with the age old issue of corrosion in the thread but as said if you re-build with copper slip it will prevent it happening again. If Questmead cant help you try Techcraft motorsport.

Questmead, but not sure they stock them.
Mine was seized last year. Bolt undid from thread but would not budge through tube sleeve. Applied heat to try and free it but no luck.
Ended up having to cut through sleeve & bolt to remove.

REAR AP

Bolt - # CP3439-110

Tube Sleeve - # CP5144-144

Helicoil for bolt (# CP3439-110) - # CP3714-116 (M8 x 1.25)

Copper grease new bolt generously prior to fitting inside new sleeve.
