Re: Front right side brake sticking

Well, I would be very happy to find that the problem is because of a cheap part, can't wait to find it, all I have to do now, is to put the ceramic paste on the back of the pads and try to put some on the piston also, under the rubber seal, if I can get it off safely and of course, put it back on . I see how it behaves and I'll keep you updated.

Re: Front right side brake sticking

Yes, all information about sticking brakes from anyone is very welcome on this thread.

There's always the possibility that we have a number of different issues. It's probably something common though.

Re: Front right side brake sticking

I got to the garage after a decent length of drive this morning. I heard a little squeak as I approached, so wasn't surprised to find the front-right disk was hot. The front-left was cold.

However, looking at the back, the rear-right was cold, rear-left was hot. So both brakes on the diagonal circuit were hot. This points towards the master cylinder or similar.

Anyway, I left the pads with him (that need replacing anyway). Upon trying to change the rear pads, he's found that both rear calipers are completely seized. Two rear calipers have been ordered.

So these need changing anyway as they're knackered. But is it possible that the stuck rear could be causing the front to rub? I can't quite imagine how myself, but we'll see what happens with all new pads (+fitting kits) and two new rear calipers.

The front-right caliper was previously changed, so only the front-left is not new.

We'll see what happens. All ideas welcome.

Re: Front right side brake sticking

Good info, let's see what he says about the master cylinder. Next time I will check also the rear ones.

Re: Front right side brake sticking

Just been on E-Learn - it shows the electronics associated with the braking system.
With what you are getting with the hot discs at opposite corners I can see it being a fault in the circuitry and /or the hydraulic valve.

It looks that it could cause problems with anything that relys on it if it went tits up, ABS/ ASR/ ESP? all have an input to this valve.

Dont envy you with this one Doofer

Re: Front right side brake sticking

I'll have to dig out e-learn and have a look myself. I'm in the dark on all this, I just want the bloody thing to work.

If it is the ABS/ESP etc then all the different systems should come down to a number of actuators that somehow apply or release the brakes.

Now, isn't the ESP at least capable of braking individual wheels? If that is so then doesn't the fact that the two opposite corners (hopefully) mean that it's unlikely to be anything ABS-connected? ...unless two actuators are independently buggered! How does the ABS system apply the brakes anyway? Does it even operate via the fluid?

Re: Front right side brake sticking

Doof - From my understanding of "Dual circuit brakes" it has rthe ability to pull the car up in case of one circuit failure by having 2 circuits which apply pressure to diagonal wheels , this keeps the car (supposedly) in a straight line .
On the E-Learn circuit are solenoid valves which I assume give the ability to individually break or release during times when the ABS/ ASR are deemed nessessary by the relevant ECU.
Dont wish to build up your hopes but a bad earth on a relay is far more preferable to anything hydraulic? Where they are I`ve not had chance to look anywhere yet
I think that with the cars predeliction towards bad earths(ie steering pump) its as good a shot at it as I can see. BOL

Re: Front right side brake sticking

I'm going to risk cursing myself, but I've only done one shortish journey after its new pads, fitting kits and rear calipers and the disks are... cold.

Watch this space. I don't think it's fixed, it's just playing its evil intermittent mind games with me again.

It may not have been the calipers - I'm thinking the fitting kits. I'll take some photos of the old ones tomorrow, they're not only filthy (as they would be), but they look a bit deformed. In fact they look like they've come out of a shipwreck. I'd bet they're as old as the car. Mintex recommend changing them every two years.

Ah ye of little faith!!
Did the calipers come from the Mary Rose?

Re: Front right side brake sticking

I didn't see the calipers, but the pads have rusty rings on the backs of them. They were undoubtedly knackered. I guess it's got a better chance of working if the moving parts are physically capable of moving.

Fingers crossed...

In the good old days the solid discs were given a hardened "case" to a certain depth and could be skimmed a little , with the advent of vented discs the case hardening was stopped in favour of normalise and temper I believe . This gives a relatively even hardness across the section of the disc. If my memory serves me right the skimming up of discs is not done due to the probable warping of the disc under the heating during hard breaking.
The old type solid discs had a minimum thickness you could go down to , the modern vented have a minimum thickness they can "wear "down to.
Just done a little delving into the manual looking for something else and noticed that there is a grinding tolerance on the discs for future reference:--
Front--1.9 8v--- New=25mm thick-- min after grind= 22.35mm
Rear-- 1.98v---New=12mm thick---min after grind10.35mm
Front--1.9 16v--New28mm thick----min after grind 26.35mm
Rear---1.9 16v --new20mm thick----min after grind18.35mm

2.2 16v same as 1.9 8v

Re: Front right side brake sticking

Oh bum. Saw the black dust on the front right wheel today, after I meticulously cleaned them all last weekend. Did the "dab fingers on disks after a long drive without braking" test.

Test results: Front right and back left: hot. front left and back right: cold.

So, other than any scary ABS-related expensive-sounding problems, the only thing that isn't new is the master cylinder. So that will have to be the next thing to get changed. Got my photos of the thing, will now see if it's a Vectra part. The header tank does have a GM logo on it, so perhaps at least it won't be silly Fiat parts prices.

Re: Front right side brake sticking

I've changed my pads last week also, but I've only had 200 miles and can't really say if it sticks or not. Even tho I check the wheels every time, for now it seems to be okay, but I'm pretty sure it's not. Changing the master cylinder is expensive, I'd rather change the pads more often. Sure, if the problem gets worse we would have to change the master cylinder, but for now its ok. I'm sure most of the Croma's have this problem but, not all the drivers/owners check the wheels
