Hi all
I have a problem with my dads 2002 diesel p38, I replaced all the brake pads last week as the drivers rear (uk) was almost steel to steel. It took a while to get the caliper piston back but it finally went and the other 3 wheels went back with no problems. 3 days later he called me and the rear drivers side brake had locked on. I stripped it down again and found that the caliper was free so put it all back together and took it around the block, when we got back the brake was hot and smelled of burning rubber. Since then I havent had time to look at it so it went into a garage today. They said that the brake fluid wasnt returning from the caliper so they thought the flexy hose had collapsed inside and replaced it. After a road test there was no change (still binding), So they stripped the caliper and made shure the piston and slide pins were free, fitted new discs and road tested it (no change). Now we are scratching our heads and possibly going for a new caliper.
Has anyone come accross this before and has anyone cured it..... and how, or can anyone shed any light on the problem at all ?
I will be greatfull for any ideas / input.
Thanks
Mark

I had a problem like yours and after a lot of head scratching it turned out to be the caliper carrier.
Basically where the pads actually sit there is a lip where the pads locate and slide along to engage the disc but after many years the surface where the pads sit had become pitted and where causing the pads to stick , and at one point the pad was permantley jammed up against the disc.
So I ended up with new discs pads and replaced the carriers as the calipers are still ok.

Thanks i will pass this onto the garage tomorrow, they have stripped the caliper and carrier down and said that its ok but this area may have been overlooked.

I replace these often with recon units I have stock piled, I'd say its a common problem on right rear, odd but its always right rear.

I get mine glass blasted and cleaned, new seals etc and works a treat

All sorted now,
Phoned the garage this morning and mentioned the caliper carrier, both me and the garage had cleaned this up and used copper slip on the pad edges and we decided that this would be the next thing to change. Failing that the only thing left was the brake modulator (quoted £2011.60 inc vat for the part). Anyway they had already fitted a new caliper before going home last night, so they road tested it this morning and its worked, the brakes no longer stick and get hot, so my mom and dad are happy again.
Thanks to you all for your help and suggestions
Much appreciated.
