Caliper Slide Pin Removal

Fritz · Apr 1, 2015

So I needed to change the front brake pads on my 02 TD4. Such a simple job I thought I'd be done in 30 mins or so. And it was other than the offside lower slide pin is seized.

After giving up trying to shift it with the carrier on the car I removed that and soaked it in Plusgas for a couple of hours. No joy.

I've tried heating it up with a blow torch (tentatively as there's lots of flames when I do). Also no joy.

I've hit it (quite hard in fact); tapped it; sworn at it (lots); tried asking it REALLY nicely to shift but it's just not playing ball.

Only other thing I can think of (I actually read it on LZ somewhere) is get the pin in a vice and twisting the carrier but that sounds like a sure way to shear the pin off as it won't rotate or move inwards or outwards at all.

Any other ideas that I can try?

If I really can't shift it is it possible to buy just the carrier? I've had a little browse and can't seem to find one. Lots of calipers at very expensive prices but no carriers only.

Such a silly little fault but such a big problem caused by it!!

WOW I never had one that bad , what I have done in the past with studs that are hard to get out is to heat it up with a gas torch and get it really hot but watch the brake fluid hose unless you take it off which is probably better and when I think it is hot enough is to drench it in either plus gas or WD40 it will probably go up in flames , but this has nearly always worked for me, as you heat it up it expands and as you drench it shrink's back I not it is not by much but it does, and get the correct 6 sided spanner or socket on it not a multi as these can round the nut top off

Carrier part numbers are SEE100320 for the RH and SEE100330 for the LH

Hey thanks for the replies guys.

@Teddy I'm going to give the extreme heat route a try in the morning after a thorough soak in Plusgas. Do you mean leave the retaining screw in and turn that instead of the actual pin?

@TD4, thanks for the part number. Seems worse case I'm looking at a further 50 quid and I think that might be where I end up going. Not the best result but could be worse I guess

Hi,I had exactly the same problem last weekend I tried everthing in the end i heated It up in a vice and gentle tapped it out fom behind with a small hammer and chisel came straight out.I ordered new pins should arrive tomorrow so I can get it back together for the weekend.not had disco long pads were at the limit discs too.annual job I think strip down clean up and regease.

Had this before - the lower pin has a rubber sleeve which adds to the seizedness and makes hammer blows ineffective - the rubber just gives a little and damps the blow. As you try to withdraw the pin, the rubber rides up on the pin land and jams.

You have to get the pin in a vice and rotate the carrier as suggested. Once you've got it to turn, lever the pin out of the carrier using a prybar against the vice. Steady force, not hammer blows. Don't worry about shearing the pin - think how much force it takes in normal use.

If that doesn't work, you'll have to do what I did - get an impact wrench or similar on the hex head of the pin and spin the arse off it till the friction causes the rubber to melt enough to remove the pin. Clean out the hole with a 10mm drill bit, rag and brake clean. New pin might be an idea, but until you can get one just use the pin on it's own - the rubber sleeve doesn't do much.

Do what a mech did to mine, just drill a small hole from the other side nd use a drift to knock it out, mines been that way for 3 years or so, and not caused a prob, and on the plus side you can squirt lube in through the same hole, and its there if it sticks again, if you want you could even find some kind of plug to reseal it

Well that was fun......Took a bit of everyones advice and finally got it shifted

After the small thermo nuclear explosion created through heating an drenching the pin started to turn; only about a quarter turn but it was movement. It also added the added benefit in that I no longer need that haircut that the missus keeps banging on about!!

Anyway movement. Next step the impact wrench to get it to turn freely but still no movement in or out.

finally drilled a hole in the back of the carrier and pushed the pin out from behind. Sealed the hole by tapping and plugging.

Happy days.

Now, the pins out and cleaned up but the end of the pin has a kind of collar and looks like there used to be something there that is no longer. Is this the rubber sleeve guineafowl refers to? Reason being I really need to use the car over this weekend so if I can re-use the old pin temporarily that would be great but its the brakes remember and I wouldn't want to put myself or anyone else at risk.\

Well done. Just clean up the pin and bore, lube and use it - the rubber sleeve is just a damper to help prevent click and squeal.

The rubber sleeve/ collar can be left off temporarily. Rover used the same caliper without the sleeve. I would guess it's for noise reduction anyway. I've used Rover pins before now to get the vehicle mobile again.

That's brilliant, many thanks.

I've ordered a new set but of course they aren't going to get to me until Thursday of next week due to Easter.

At least I can get out over the weekend.

Thanks to everyone for your help

do not tell me you had your head under the wheel arch when the fluid went up in flames we will have to think of a new name for you. glad you got it done!

Hi, I realise this is a late reply, but I have had many problems with these little gits. I now buy new ones from a supplier, this time I have also bought a caliper as well as my one is starting to look a bit for worse
