Hi all looking for some ideas , after my 2005 RR SC sport had come back from its MOT I noticed a smell of burning brake coming from the rear LHS, I striped the rear discs off and inspected the EPB all seems to be ok . The discs and shoes are fairly new and seem to be working fine. Adjusted the parking brake as recommended in manual discs spin freely put wheels back on drove 8 miles to work seemed OK , drove back home and the smell and the heat is back. I hadn't even used the EPB.
Anybody had the same problem.
Cheers,
Paulo

How’s the brake caliper? I’ve seen calipers with binding pistons which show up when the pads are replaced. If you think that a pad may be installed for years as it wares down, the piston pushing it onto the disc is slowly having to protrude further out to compensate. The piston exposed to the elements deteriorates as does the seal and when you fit new pads that piston gets pushed all the way back in to the caliper, with any rust and crud. You then put your foot on the brake and the piston moves under hydraulic pressure to contact the pad. The disc then has to push the piston back in with little effort and it just isn’t enough. 2019 5.0 SC SVA (Current)

I’ve had exactly the same as Brit Plumber describes, sticking caliper after new pads fitted. Only cure was to have the rear calipers replaced
The pads bind all the more as the disk gets hot, then, when it’s been given a chance to cool down, the wheel spins freely until it starts to bind and heat up again.

Thanks for your replies , looks like new calliper then.

Think I paid my indy about £140 per side for genuine rear calipers. (fitted)

Paulo, seeing as you know how to strip the brakes down, how about taking the caliper off, removing the pads and put a lump of wood in the caliper and gently press the pedal until the piston comes out. Not enough to pop out and lose fluid but enough to stretch the rubber boot and inspect for splits or perishing. If it’s ok, clean it with soapy water and dry, you can add tyre dressing to put back some silicone into the rubber too. You can then see if you can lift and slip back the boot to see if there’s corrosion, clean it up and push back in. Reassemble and go for a spin, if it’s worked you may get a few months or even years out of it but you’ll know it’s the caliper if it comes back. 2019 5.0 SC SVA (Current)

Probably worth checking the caliper is not sticking on the guide pins as well, but that would probably show up with the outer pad worn more than the inner one.

I know the pins are moving freely, I did think about buying the repair kit, new piston and rubbers but past experience tells me to go the hole hog as they last for a while but tend to develop problems. I have ordered a new calliper and repair kit for the old one as a spare,
Cheers for your suggestions I will update when completed .

Sorry for the delay but didn't get a chance to fit the new calliper , all done now though and all is good , pins where fine just the calliper. You where spot on when you said about them binding and when they cooled off they where fine which caused me to look at the handbrake adjustment and of cause they where filled with burnt dust but from the brake pads not the shoes.
Thanks again,
Paulo
