Omega General Help / Re: brake pads

Thanks guys! The car in question is an early Ď99 2.5 V6, so I guess that settles that :)

This seems like a suitable thread to join rather than starting a whole new one for a simple question

Can anyone tell me what's going on here? On the left is Brembo, on the right is Ferodo. Both listed as fitting Omega B(1994 onwards). I was hoping to use the Ferodo pads now and keep the Brembo ones until the Ferodos are worn out

Am I right that they can't both fit the same caliper? Those ears on the Ferodo pad don't seem compatible with the Brembo and vice versa

I am a good 100 miles away from the car and won't be getting to it until Sunday, so I thought I'd ask here in case it let me initiate swapping the pads if they're wrong :)

And I've had a thought about what you said about scrapping the Astra, so today I decided to look for the headlight fault. Turns out that I'm an absentminded idiot and there's no problem with the headlight wiring - I changed the wrong bulb  ::)

;D ;D

I laugh because I spent quite some time (including getting the meter out and fishing around in the fuse box) trying to work out why the headlights weren't working on a BMW 118 .. until I realised that they do nothing unless you turn the ignition on  :-[ :-[ :-[

Today I really feel that I've let not only myself but also the forum down  ;D

There's nothing quite like making yourself look an idiot in public, written media  :D

The Omega needs a lot of pedal movement. If you're used to Fordesque fart-and-it-locks-up shite, it will be an unusual sensation.

I don't think that's it - I spend most of my driving time in old Vauxhalls, 4x4s, vans and trucks!

I wonder if maybe I've got some particularly rubbish pattern pads. Probably a case of me overthinking it and jumping to a silly conclusion instead of finding the most sensible and likely one

Properly maintained, the Omega on standard GM parts (pattern standard brakes for the Omega are universally shite) can fire the ABS at 130mph in the dry with good premium tyres 235/45/17.  In addition, they can handle 10 x 100mph to near standstill in the time it takes to get across Milton Keynes.  Granted, they are spent after the latter.

To me, that means the brakes are perfectly fine for road use.

They need work for track days to prevent overheating (and track pads)

I'm going to guess that mine are rubbish pattern parts then. Problem solved, probably.

I'll search for Genuine GM (or whatever it's called now GM doesn't own Opel)

Poor quality pads?

I'll have to assume this and change them. I'll have a look in the history to find out what they are and when they were changed. They've been on the car since before I bought it in 2018.

They just feel very weak, to be honest. Even with a lot of pedal pressure it just doesn't seem to stop urgently. The pedal feels a bit light too. Not exactly spongy.
It is however the only Omega I've ever driven so I don't know if it's like the rest and I'm just being paranoid

Clearly not driving it properly  :D

I'm not ruling it out!  ;D

So yeah, I suppose it is too good to scrap really, even with two dented doors. I'll make an effort to find a buyer

The pedal is progressive, allowing smooth braking, due to type of car it is. Omega was always aimed at motorway mile muncher and allowing a smooth drive.

Stamp hard on them and it stops, MotherT always said her Omega brakes were poor, until I demonstrated that stamping on the pedal as per an emergency it stops bloody quick!

3.2 here, no complaints with brakes.

To the first point, I donít think that that is particularly the case.


And if everyone else has good brakes, it must just be mine that are rubbish

Is it progressive?

It is, I suppose. Before I bled the system it wasn't, but you'd expect that!

Maybe Iím just used to cars with much better brakes then. They feel absolutely terrible to me! I have a Mercedes ML from the same era and thatís obviously a heavier car but the brakes feel better and seem to stop it better. I drive Class 2 trucks that donít feel much worse than the Omega!

I have bled them and it improved them, but not as much as I had hoped it would

Very much doubt the wheels will fit, they could be persuaded with some spacers but that could mess things up.  :-\

They do fit - I've already used the car with identical wheels. This will just be a spare set to use the tyres up, since they're good

Cat N could probably pass an MoT... not fixing it is plain lazy if fundamentally ok ???

No the brakes won't fit. Easiest option is to fit the front callipers from an early base model Monaro/Pontiac GTO... same sized discs as the Omega and same fitting for the calliper. Anything more involved and you're talking £££ and effort. ;)

It did pass the last MOT as a Cat N, but now it has more faults. It's not rusty and the engine and gearbox are good, are what I meant.

It's in a shabby condition, reports an emissions fault (although I've put it through the last few MOTs like this, just turning the light off before the test), it will need some suspension work for the next MOT and one headlight mysteriously stopped working a few weeks ago. I have changed the bulb, but no difference.

At the same time I got a crazy bargain on a car I've wanted for a while, so I've replaced it already

Hi all!

I'm struggling to get much reliable info online. Basically the thing that has always disappointed me in the 'mega is the brakes. I have a 2005 Astra Turbo that has been written off (Cat N) and I'm planning to scrap soon. I've always loved the brakes in that.

I'll keep the wheels and tyres to use on the Omega, but is there any chance of using the brake calipers? Or would there be no benefit?

I believe the Astra has 308mm discs on the front and the Omega has 296mm discs, but I can find scant other concrete information. I don't have the two cars together to compare right now, and I thought someone here might know. If not, the Astra goes to the scrapyard on steel wheels. Shame for a fundamentally OK car, but it's not worth spending the money to sort it out

Thank you

2.6/3.2 exhaust manifolds are a worthwhile upgrade.  :y

Thanks, how worthwhile are we talking? Best to put them in with the cams or can they wait?
Is there anything else that should be done along with them?

15
Waste of time and money  ;)

I think that you're probably right....I just think that since the cams are there anyway and I want to change the belt and tensioner it's worth a go.

The 2.0 turbo has way more potential than the 3.2 for out and out power, so if I was doing an engine swap, that's what I'd do
