Omega General Help / Re: Brake pad not contacting whole disc face

« on: 12 October 2020, 06:58:24 »

I took it apart yesterday, everything checked out ok. Then decided to take it along a long back road near me, and give the brakes a few work outs, I should really remember currently my abs isn't working lol as I done an emergency stop and locked both wheels up in spectacular fashion, ended up with a flat scrubbed into one of my tyres!

Had a bit of a fling with a tesla back down the hills and some hard braking ensued so hopefully that had helped!

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?

About just over 100 miles.

I'm quite particular about rebuilding brakes or anything so should be ok, but I'll double check it all again, just in case the slider is sticky. The make of pads was delphi.

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..

Never heard of that, what are they coated in? I know they usually coat with a light oil for storage, but I wipe that off only on disc face, obviously it wears off and the rust starts on the edges and hub bit, plenty of copper slip on mating faces however.

Are the discs/pads correct for the car?

https://photos.app.goo.gl/WC2KLh3A2rhWirVAA

3.2 v6, but 2.6 should be IDENTICAL.

Discs should be 296x28. Calipers and pads shouldlook like above. 

Yep, double checked sizes and against old parts, here's the order details:

Brake Disc Thickness [mm]:   28 mm
Brake Disc Type:   Vented
Centering Diameter [mm]:   70 mm
Depth [mm]:   58,5 mm
Diameter [mm]:   296 mm
Minimum Thickness:   26 mm

Any idea why brake pad is no rubbing on whole disc face.

I've just renewed pads/discs and checked sliders were all ok, not seized or sticking, cleaned the whole calipers etc.



Strange how a pad could contact just over half the disc!

The rust spots are just where rain got in the wheels

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

I did change both track rods on one side, if that's what you mean? I plan to change the O/S one as soon as funds allow, and get tracking done.

It certainly feels like the play is up nearer the steering wheel, and can feel it if I rock wheel up and down, or side to side, like you would on your road wheel. I'll certainly check the box idler arm again, as I know how these things can play tricks on you. Funnily enough I just replaced the whole passenger side steering arm from the idler to the hub as outer track rod was getting a bit loose, and inner asn't far behind, strangley enough I had it like this for more than a Year (don't do much miles) and couldn't remember any obvious feeling of play at steering wheel.

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.

Would you "see" play in that just rocking the steering, does it need to be checked another way? I didn't see any movement looked tight.

Omega General Help / Play at steering wheel

« on: 02 October 2020, 07:15:28 »

Last Month or so I've noticed a slight play in steering wheel, sure I heard a clunk noise from it as well one day while turning, and could almost feel it through my hands.

I done a check of the steering box yesterday with car up on ramps and assistant rocking steering side to side (Engine on). Couldn't see any issues with any of the links or anything around the box, no rot near the box, but I could feel a slight clunk through the steering arms, which appeared to be coming from behind the bulkhead area.

I put my hand up under the brake pedal and could feel the UJ thingy and again I could feel this slight clunk but it did seem up more towards the steering wheel. So I'm guessing it's a new bearing at the steering shaft. Has any one done this before is it just a case of steering wheel off, or do I need to change the whole adjuster unit with bearing incorporated in it?

Thanks

Andrew

Excellent, thanks all for the description and explanations of that number, I wasn't sure what the number itself correpsonded to on the actual VIN number but that explains it.

On some of the online parts catalogues there is a, what I am assuming to be, a part of of a chassis no listed saying for [part] [VIN code] like this:

FOR TILTING STEERING COLUMN V1000001-

https://opel.7zap.com/en/car/v94/l/0/6-1/

My chassis number is W0L0VBMXXXXXXXXXX

X being a long number. how does this V1000001 correspond to the chassis number?

Thanks

Standard size brakes aren't an upgrade

Unless you think that drilled discs are somehow special...

Sorry I think I said uprated, but you get the point.

Thanks all for input so far, I wasn't sure if it was worth the extra cost for uprated brakes as I don't really need them if I'm brutally honest. I have been used to my brakes being a bit wooden and I know it is front discs need changed, I rebuilt all the back with new GM discs and pads and it improved the brakes quite a bit. I might just go down the standard route thinking on it.

Cheers

Hi

I have known for a while my front discs are buggered, still chunky but one of the calipers was seized a while back and the back of both discs are pitted. Anyhoo I'm thinking of getting a set of mintex front pads/discs. Is this a good buy or recommend any other ones?

Omega 2.6 02.

Cheers
