I bought a Claude Butler Cape Wrath bike a couple of years ago in the uk - Long story but it never
got used and has been stored in my loft. I have decided to sell it but the back wheel is sticking
- I think its the Grimeca disc brakes but I haven't got a clue how to free them off. Can anyone
guide me on how to free it off or alternatively do Halfords or similar offer a service for bikes
and if so what will the cost approx??

If it's a cable disc, check the cables are free - they sometimes bind if left stood for a while.

Just undo the cable end clamp bolt on the brake calliper, check if the cable moves freely by pulling
the lever, then pulling the cable end back through. If it's stiff, remove the inner cable from the
outer and apply some light oil to the inner. Re-insert, run it through a few times until it's moving
smooth again, and re-clamp the cable. Make sure you clamp it with enough cable tension, then fine
tune it with the little adjuster knob(s) either at the lever end, the calliper end, or both.

Hope this helps.

Well, i think if they are truly stuck on the rotors, perhaps some penetrating oil may free the
pads. Of course, after they are free, you will have to scrub the rotors and sand the pads to rid
them of the oil.

After you get the rotors off, make sure the hydraulics are still in order. find a piece of wood
that's slightly smaller than the rotor width, place it between the pads and squeeze. the wood
prevents too much piston extension (assuming similar to car disk brakes here) and is also a soft
non-scoring surface. if the hydraulics stick a bit (should self return a little bit) then work them
a few times (rebuild kit may be needed) and check for fluid leaks. as the piston will most likely
self adjust to the width of the wood, some fluid may need to be bled out to allow the rotor to fit
again (then top off fluid as necessary).

At least this worked for a friends car, i can only assume bike disk brakes are similar.

Nope - keep oil away from the pads if you want them to definitely work again, especially a
penetrating oil FFS.

Perhaps the pad material for cars is different then as the car i did this on doesn't seem to be
lacking any braking power.

Maybe that's the case, maybe it's something else. I got fork oil on my pads (small amount, dripped
on rotor first) twice in a couple of weeks, and luckily, they survived after a cleaning and a scrub
up on a flat bed bench sander (cleaned up the rotor too, did the usual wet mud thing afterward as
well). When I got a little brake fluid on my pads one time (on for only a few seconds before they
were dumped in dish liquid and water etc.) they were

just *that, so, you are likely to ruin the pads. You may get lucky, you may not, hence my use of the
phrase "if you want them to definitely work again".

I have just got new discs put on yet they seem to be making a screeching

noise when ever the brake goes through the mechanism yet if I touch the brake itself (outside of
course) and put a bit of pressure on it, it stops and the wheel seems to run a tad freer can anyone
who has any experience with discs give me the benefit of your knowledge (apologies for the vagueness
of the question)

thanks
