Title: rear brake caliper ?
Post by: raywilb on 28 March 2016, 08:12:41
I recently put pads on the rear brakes & when replacing the wheel the caliper had moved round slightly -it had none of those small flat head bolts keeping the caliper in situ. I was hoping someone will be able to tell me what size they are .

  sorry I meant to say the wheel drum had slightly moved so the wheel bolts were not lining up right.  its the small bolt that retains the drum in situ that are missing.  Ive looked on ebay but cant find any

On rear of Omega, the only thing that keeps caliper in place are 2 dirty great bolts, holding the caliper to the caliper bracket?

Why ebay?

Try your local dealer. EPC will list them.

He must mean the countersunk screw that retains the brake disc when the wheel bolts are removed.
In which case, it's a short countersunk setscrew. Without checking mine, I think they're M8.

Yup that's the one  :y

Normally end up chewing the head of with a knackered screwdriver so end up drilling it out  ::)

I'd call it "a nice to have" Ray  :y
Not really essential so personally i'd just make sure the handbrake it fully off, spin the disc until all the bolt holes line up properly and bolt it back together  :y

If you do get another screw, just stick the very slightest touch of copperslip on the thread when you re build it  ;)

Essential if you forget to release the handbrake before jacking...

To explain: the handbrake shoes, and therefore disc/drum rotate as they are lowered, whereas, relatively, the driveshaft/hub don't. Pretty much guaranteed to chew the thread on the last bolt as you remove it.

I normally have all my bolts finger tight when the wheel is on the ground before jacking but fair point though, I never looked at it that way before  :)
