Caliper Carrier

[Cruiser459]

Looks like the GS is going and we are keeping the RX.

A few weeks ago we noticed that from time to time the osf brake on the RX seemed to occasionally "slip" on application. Had new brakes all round last year and lightly used since

No problems with stopping at any speed, it just sometimes feels as if the anti lock has kicked in for a fraction of a second on that wheel. Might happen once or twice at most in a day and wheel never locks up or anything remotely like that.

MOT passed without any advisories but garage did a caliper overhaul and thought that had solved the problem.

I noticed yesterday though that sometimes there's a very light rubbing noise from the osf (I'm having to drive with the window open while we sort out the a/c compressor!), with the noise going when the brakes are applied, and the noise slowly returns at times.

Called them this morning and the garage says it must be the caliper carrier.

Two things please!

A) Does that sound right

and

B)is it expensive????

They tell me its an easy fix, about 30-45 mins and they are happy to fit if I can source

Thanks

Caliper carrier? What did they say was wrong with it? It does nothing much except sit there bolted to the hub letting the brake caliper do it's work, about the only thing it could do is fracture.......

If they mean it's corroded and the caliper is sticking then it just needs a good clean with a steel brush and lubed with copa slip.

It seems to be a process of elimination and I confess I'm losing patience with them. They've overhauled or replaced everything else and say that's all there's left!!!

The noise is getting worse and finding a carrier from even a breaker is a challenge!

[Boxbrownie]

Sounds more like a sticking caliper than anything else, no carriers available as there is nothing to go wrong, its just a cast lump of iron!

Unfortunately a lot of expertise has gone from the garage trade, to much reliance on replace to repair and hardly ever a proper investigation is carried out to find the original fault.

[Boxbrownie]

Is there anyone on the forum that can post a page from the repair/parts manual regarding the brake/carrier components?

[Cruiser459]

Hi again. I'm going to replace the overhauled caliper. They did an overhaul on it and soaked it etc,but within a day or so the initial occasional grating returned. Now it's pretty much a constant noise

Can't disagree that now it seems as though everyone wants to replace rather than fix!!

Should I be looking to replace both front calipers at the same time?

Hope this helps. Doesn't look too complicated really.

[Boxbrownie]

Providing the other caliper is working corredctly there is no need at all to replace/overhaul both, just the one that needs it.

I wonder if they looked more at the caliper than the sliding pins and components, if the floating caliper does not move freely it'll cause all sorts of issues.

[Cruiser459]

I've bitten the bullet and sourced a carrier and a new caliper. Provided they arrive as promised they will be fitted on Thursday and hopefully that will be the end of it!

[Cruiser459]

So a new caliper has been fitted and the caliper carrier replaced. No change! Pads and disc fine, no abs light flicker, caliper fine, no wear marks on old caliper carrier.

Any suggestions? Is it worth banging on a new set of pads to see if it's them??

[billgatesisaconman]

I agree with Boxbrownie ... If they didn't already I would replace the slide pins using Lithium grease(if needed new boots)

I would avoid using copper grease on the pins or near the caliper piston seals ...

[Cruiser459]

Got there in the end!

Turned out to be a worn abs reluctor ring!!!!

[Boxbrownie]

Great news, did they replace or just clean it up? Usually a good brushing with a hard wire brush will cure corroded rings, a bit unusual they didnt pin point it on the OBD as an ABS fault though.
