Code R Caliper Leaking

Hi, I think my front Code R Caliper is leaking. Whenever I inspect my brake pads and front caliper they are always covered in brake fluid. I use my weed burner to get the fluid off and they don't squeak for a while but whenever I go to use by bike again they are squeaking like crazy. I tried taking apart and then reassembling my caliper but that didn't do anything. What can I do to fix this?

    You need to find the leak source first, is it at the hose connection or one of the pistons seals or at the calliper split line (if that calliper has one) what did you replace when you took it apart?

    That won't clean the pads by the way.

    I think it is one of the piston seals, when I took it apart I just inspected everything and then put it back together.

    As for the weed burner, brake fluid is flammable so when you use a weed burner or something similar there is a lot of smoke and eventually it stops and then you sand it and it stops squeaking. The problem is that the squeak keeps coming back and the pads are covered in brake fluid.

    How old are the brakes? I'd be looking at getting them repaired/replaced under warranty if I could.

    You could burn off the brake fluid on or close to the surface and then the fluid absorbed further in migrate back out, though you need to fix the leak first, clean it all up then put a piece of toile roll at each suspect place and squeeze the lever progressively until you see on of the pieces is damp then you'll know where the leak is.

    I got them second hand so I don't have the receipts or anything.

    I have done that, somehow it decided that it is no longer leaking since the caliper overhaul, even though it was still leaking after that. In other words, it is now fine.

    Er so your thread title should be 'Code R Calliper Not Leaking'?
