Hi all. Need some advice please.
my rear pads need replacing and having had a look the retaining pins that hold the pads in are fairly rusty. Are these reusable or are they suposed to be replaced at same time.
Also is is best to stick with vauxhall pads or can someone recommend an alternative.
Thanks in advance.

Eurocarparts for mine (£15 iirc).
And just de-rust the pins with wire brush.
Done. :y
-
AS Webby said :y :y :y :y
-
Depends on their condition. The pins are quite expensive, but are pretty robust. The spring normally rusts through at the rivet.
-
Eurocarparts for mine (£15 iirc).
GM for mine, about £10 + VAT.

Was that TC or non TC price?
-
I had to do discs and pads on mine ready for MOT. The genuine VX parts came with new retaining pins etc. I don't know what the TC price is for pads alone as I bought the whole lot but it may be worth asking what comes with the VX pads before you decide?

TC. Note that you have to provide the part number now, as they are no longer on the TC website.

They would be OE pads, quite expensive (but some say worth it), about £50 IIRC.
If you need the pins/springs, the OE ones probably make a lot of sense.

I have a set of unused pins/shims........only problem is they were too short. I reused the old ones after removing the assorted 'crud' with a wire brush. :y

ECP do the pins and retaining clip thingy. only couple of quids but as said before be careful as they may not be the right size.... mine were luckily :y

thats because they were for the older solid disc rear set up,yours are vented and has wider calipers :y

So did the clowns that changed Mike Dundee's discs which almost had disastrous consequences a few years ago.

I'll have to remember that when it comes time to do my pads. May as well get them all done at the same time.

I've just bought a complete rear brake set for £66 which includes discs, pads, shoes and the fitting kit!! :)
It's probably made from cardboard though at that price, but hey ho funds are tight and if it gets the old girl through the MOT.... ;)

Looks like tc price to me,minus vat. I could be wrong.
-
There are two types of fitting kits short & long both pins and springs
-
Thanks for all the advice.
Did the pads today as it was a nice day for once.
I would strongly advise the use of a proper punch to remove the pins and not a nail.
However both of the springs were missing! Is it vital they are fitted and what is there function. I will get a set as the pins were very rusty anyway but until I do can someone advise.
Thanks

Which springs? There's just the sprung anti rattle clip on top of the pads. :-\
-
They are antirattle only I think, but I would feel uncomfortable if they weren't there. But should be OK to drive around until you get some

Until replaced mine, it was more of a token gesture towards anti-rattling ;D There wasn't much left. :y

Your comments about vented rear discs and solid rear discs has me worried. I have just replaced my worn vented discs (2003 3.2 Omega) with new pattern solid discs. Is there a risk of the pistons coming out of the cylinders when the pads are worn?
-
I believe so,yes. ;)

Why? As GixxerChris eloquently put it a while back ..... when asked if you want vented or solid, it's not a choice like do you want sugar in your tea?
If you have vented discs at the back, you NEED to replace them with another pair of VENTED discs! The solid discs are half the thickness of the vented discs & when the rear(?) pad wears, the piston behind will fall out & spray brake fluid all over the place & you'll have no brakes!
FIT ANOTHER PAIR OF VENTED DISCS NOW!
-
Methinks a mixture of limited technical understanding and knotted purse strings ;D ;D ;D ;D
Why else replace one type of disc (as fitted as oem) by a different type? ::)

Yep ask Mike Dundee, it happened to his car.

It's a shame VX didn't make the two types a different diameter so it wouldn't be possible for such a cock up to occur :-\
Terry,get them changed ASAP mate before something bad happens
-
Vx dealer gave me solid front discs for the 53 plate Corsa, when they are actually vented on the ABS model.
No apology from them. :-\.....Typical.
The vented discs I exchanged them for are are much wider. :y

I should hope so. Can you image how thin each side of the disc would be if you made a vented disc as thick/thin as a solid disc :o :o :o :o ;) ;)

Yes, and they dont need to wear much either.
The outer piston will pop out dispensing brake fluid everywhere. I had to do a quick repair to Mick Dundees after this happened in a field in York!

Good word! Is the the same as spraying? ::) ;)

Today I measured the disc thicknesses; new solid disc .476". Old ventilated disc .703" where worn, .750" on edge (unworn). I shall change them Saturday. Thanks to you all and the forum for pointing this out.
I did once lose all brake fluid on a Peugeot 505 estate. The rear brakes were self adjusting drums, and when the linings wore out the pistons popped out of the cylinders, resulting in total loss of fluid and thus of brakes. The incident is memorable in that I drove the car home towing the wife in her Senator, acting as a brake. She happened to have the computer on fuel economy setting, and was amused to see it recording an amazing high mpg figure.

Glad youre in process of getting it sorted mate :y
When you replace the discs it says in the guide to back off the shoe adjuster...... couldn't you simply leave the handbrake off and that will allow the disc to come off? :-\ ive only done pads so far :y

Absolutely. We've seen it before.
Additionally, you may need to inform your insurance that your have "modified" the brakes, as its no longer to spec :'(

Likewise & I've had an Omega & Senators for over 15 yrs ::) ::)

You might be lucky :-\
When I have replaced worn rear discs I found that the brake shoes had worn a grooves in the drums and I had to back off the shoes to get the drum/discs off.
-
....
..... I found that the brake shoes had worn a grooves in the drums and I had to back off the shoes to get the drum/discs off.
The only time the shoes should come into contact with the drum is when you apply the handbrake when you are stopped (maybe a few handbrake turns ::)). So, how do the shoes wear the drum?
-
Fair enough :y I took the discs off my old breaker car and replaced them and the shoes didn't need backing off. :y
Anyway, thanks for answering that.... sorry for hijacking :-[
:y
-
Thanks for the advice. I always back off the adjuster before I attempt to remove a brake drum. There is often a lip of unworn brake drum on the inner edge on which the shoes can catch. Then the drum sticks, hammers are used, then tyre levers, and finally the shoes break the retaining spring pins and the whole thing falls to bits. So now I always slacken off the adjusters first.
In answer to earlier questions, I had a pair of new drums kicking around that I had bought for a 2 litre job but decided the existing drums were OK. Then I overhauled the 3.2 handbrake, and as one disc had a tiny edge chip I decided to fit the spare pair. Like others I had assumed all Omegas rear discs were interchangeable. They fitted all right. Big mistake. Luckily I read the thread.

Agreed ..... for a car that uses the drum for the foot brake. The Omega doesn't ;) - it uses the disc to stop the car & the drum to hold it, when already stopped. :y

They fitted? ??? Didn't you notice the huge gap in the caliper that you fitted the solid disc into, that previously had a thick vented disc in it? ??? ??? ???

In reply to Andy B, handbrake drum wear occurs in MOT tests, hill starts, and when the wife forgets to release the handbrake. Also when someone leaves the car parked for a week with the h/b on and it sticks. And in emergency stops; and when my son loses his brake fluid and brings the car home on the handbrake. But I agree, in general, handbrake shoes and drums should get little wear. They are designed to last the life of the car - seven years.

Can't argue with Andy B's theory.
All I know is that I replaced the rear discs on both my Omegas at around 130,000 miles (or 7 years) and there was a groove.
-
The ridge is mainly a build up of rust that has not been removed by the rubbing action of the shoes
-
....
and when the wife forgets to release the handbrake. .....
My daughter did that in SWMBO auto Astra after her then boyfriend (daughter's - not wife's ::)) applied the handbrake when being 'helpful' :( :( Daughter panicked when she could smell hot brakes!
Hill start? ??? ??? That's what your left foot is for. ;) ;)
-
i can see that on a car with brake drums. but the omegas with their discs :-\ i suppose on the omega it would depend on whether the owner used the handbrake much with it being auto
-
Surely the shoes should only rub when the wheel is turning ::) So I guess guys its sensible not to drive with the handbrake applied or use it for handbrake turns ;D ;D ;)
Ask the MOT guys to be careful on the handbrake test and it should last a long time :y
-

What he said.
The insides of the drums will rust, and any rust that appears on the parts of the drum where the shoes contact it will be swept away - even if the handbrake is never used, since the running clearance between shoes and drum is very small.
Rust outside this area will build up a thicker lip, making removal of the drum less easy.
-
This thread has reminded me,my handbrake was an advisory on the mot last year,and I need to sort it for this year (September).
Ive managed to avoid any involvement with the handbrake in 13 years of senator/Omega ownership,but my luck has now run out. :D
-
There easy enough.
The trick is light regular application to keep the faces clean, use it, and to not piss with the handbrake cable.
