Omega General Help / Re: Brake pad not contacting whole disc face
« on: 13 October 2020, 12:51:02 »
Pads are not sticking in holder, I've checked twice, they are a nice fit with no sticky bits.

how do they look now ?
How many km's has the car done since you renewed the brakes?
The photo suggests the outer edge is starting to score.
If more than 50km then I'd consider removing the pads, caliper and disc for further examination.
Is the boss of the hub clean? And the mating surface on the inboard of the disc?
What about the inboard side of the disc. What's the sweep pattern?
Are the the two set screws that hold the caliper frame even and fully tight?
What make of pads do you have?
Is the friction material thickness consistent across both pads?
Do the edges of the backplates move freely in the calipers? IE no protruding lumps.
Have you properly cleaned off any crud on the caliper itself?
Are the anti-squeal shims, if present, correctly positioned?
Are the caliper sliding pins still moving freely? And tightened home?
That picture also highlights why coated discs are beneficial over non coated - if only to avoid the premature rusting on the centre hub area and extreme edges of the discs after only a few days / miles..
Are the discs/pads correct for the car?

3.2 v6, but 2.6 should be IDENTICAL.
Discs should be 296x28. Calipers and pads shouldlook like above.
Why on earth didn't you change both COMPLETE track rods
They are cheaper as complete units vs individual parts and each time you change one of the four joints, that's another geo set up
First thing to check is the steering idler arm, on the nearside at the bulkhead, for play in the bush. Also the centre tie-rod ball-joints.
Standard size brakes aren't an upgrade
Unless you think that drilled discs are somehow special...
