Hot right hand rear wheel

[Trippy]

I have heard this squeaky-brake sounding noise this week and just now when I got out of the car after going to the beach (~2km) I could smell hot brakes. I bent down to smell the rear tyre and the wheel was just radiating heat. The mag wheel and bolts where too hot to touch. I checked the other wheels and they were not hot.

What is going on here? Are the brake pads stuck and touching the discs?

100% this is due to a sticking pair of caliper slide pins. Remove the rear wheel and see if you can rock the caliper body around. If it is tight, then you will have to remove the caliper and try and free up the slide pins. This causes the pads to not release from the disc after the brakes are applied.

My mechanic just changed the brake fluid. I didn't notice this before the change so maybe the hose got blocked when the fluid was changed?

Hi,

I had this same issue, the caliper had stuck on.

To improvise, I took the wheel off, and sprayed WD40 into the mechanism which freed it. Never had an issue since.

I did this because parts take ages to arrive here.

I'd say highly unlikely. Justin's diagnosis sounds right. I had an intermittently squeaky front caliper and rim getting hot. I found one slide pin was seized. As I was doing pads and rotors at the time all 4 caliper were checked and i found one other slide pin was getting a bit stiff and a couple of others had some surface rust. While its probably overkill I ended up putting in new slide pins all round.

Yep, I'd go for the seized calliper too...

Ok, I found a heap of useful videos on YouTube showing how to fix this. So I will just take the caliper off, lube up the pins with synthetic brake grease and use a steel brush o the the brake pad shims?

yep what 'dem uffer fellas said ^. If its not I will eat my hat :) well maybe not that far................:D

I'd be inclined to replace the pins if there is any surface damage at all. I've read advice that both pins and carriers should be replaced if there is corrosion or wear on the guide pins. Depends on how carried away you want to get keeping the D2 in top shape.

For the rear calipers a slide pin kit is around $40AU for an axle kit, so it's not going to bust the bank. The kits include 4 x pins, 4 x seals, and about 5g of grease which does 2 x calipers.

Make sure you clean out the holes the pins run in really well. They seem to gunk up with old grease. Brake cleaner and a scraper made of something that won't damage the running surfaces will help get all the crap out.

Well I sorted this out this afternoon. I took the calliper off and removed the sliding pins. One of the pins made a crunching, scraping sound when I tried to move it back and forth. I removed the boot and found plenty of rust in there.

I cleaned it all up with almost a whole can of rust cleaner and some rough sand paper. I then filled the holes and boots with brake grease and assembled it all again. It works for now but I will probably have to replace the pins. Maybe also the pistons?

Something like this (http://www.ebay.com.au/itm/LAND-ROVER-DISCOVERY-2-REAR-CALIPER-GUIDE-PIN-KIT-/220689105918?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item33621883fe&_uhb=1)maybe? Or this (http://www.brit-car.co.uk/product.php?xProd=92614)?

Either of those will be ok. I got mine from Rimmer Bros: Brake Pad Guide Pin Set - Genuine Land Rover at www.rimmerbros.co.uk (http://www.rimmerbros.co.uk/Item--i-STC1910)

Rimmer's airmail postage on that item is about £3.00 less than ebay listing linked above.

The LR Genuine parts came with TRW grease fwiw.

If the carrier is badly rusted it's worth thinking about replacing the carrier. It's LR part STC1907, OEM would be my choice here: http://www.rimmerbros.co.uk/Item--i-STC1907P1

has anyone done a seal kit on the front calipers?, noticed my dust seals are not in the best shape so might be worth a go.

Which seals are we talking here? The sliding pin seals?

[OffTrack]

Piston seals. On the pre-facelift D2's the seal kit is STC1919 which is same PN# as for the P38a Rangie.

There are a few pix of what is involved here:
