RRS 2005 Burning brake smell

dunners · Nov 13, 2018

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

Not familiar with the sport but on an earlier TD6 and my 4.4 the callipers began to seize and the hotter they got the more they expanded the fluid and seized even more.
Does the parking brake work on shoes inside a drum and the calliper on a disc for the main brake ?
I have a good laser thermometer and I could tell the disc was extremely hot and ended up stripping the callipers and replacing all the seals.
Before the repair when it cooled down the brakes were free again until I drove it for a short period of time and I started getting a vibration.
I had to use the foot brake to pump the pistons out as they were really stuck

Yes they are shoes inside the disc hub, the calliper seems to be moving freely in and out but I will give it another look,
Thank you,

Check guide pins too on the carrier and make sure they are moving freely

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
