Title: Rear brake pads
Post by: robson on 07 June 2013, 12:26:24
03 V6 back brakes   having trouble getting inside pad out is it just try and try again .I believe the pistons are push back rathet than screw back is that right.

Yes, I just pushed mine back.
Would be a good idea to take the top off your brake reservoir though before pushing it back  ;)

Got pad  out with pulling and shoving and yes cylinders just push back attacking other side now after cup of tea.

Rotate the first pad 90 degrees and refit, otherwise piston will push out when you push back the opposite one :y

Taxi Al Read your post after job done Interesting point about pushing out other pad I did notice that as I pushed in the inside piston  the outside piston moved forward so I put a worn pad in to prevent pushing piston out. A very important point that all should be aware off. I noticed that the outside pads were worn much more than the inside is this normal? One of the inside pistons was very difficult to move untill I worked it in and out a bit.

Having finished this job have read (too late) that a cut away recess in the piston should be positioned approx 23 degrees  to the horizontal Is this important what is the reason for this .I must admit that I didnt see a recess.

I believe the cut away recess is something to do with anti-squeel.

The Omega calipers have rubber gaiters which protect the pistons when they are extended. The gaiters will probably tear if you try to rotate the pistons so I would leave well alone. (& if you didn't see a recess it probably isn't there - some kind of throwback to the very early Omega that Haynes used in their strip-down).

The inner brake pad gets exposed to the most salt. Unless you make a habit of stamping on the brakes it does hardly any work and rusts in position in the caliper so yes, it is normal for the outside pad to get the most wear. :(

My rear pads wear perfectly evenly  :-\

I wonder why  ;D ;D ;D

Traction control on an "enthusiastically" driven facelift probably give the rear brakes a workout too.........

As Andy said the inner pistons seem to have a tendency to seize and one of mine was very tight.The other inside was a bit easier to move but the pad had little wear compared to the outer

perhaps read Andys post wrong he is saying that the pad rusts onto the caliper I certainly had great difficulty getting the inner pads out.

Yep.
The gaiter does a really good job of protecting the piston so what appears to be a seized piston is nearly always a rusted in pad :y

Both inside pads were difficult to remove and now changed and lubricated braking is much improved.

"Use 'em or lose them" ::)

I suspect most of my rear pad wear comes from trying to lay down 200+bhp when accelerating off the BP forecourt.
