[Rovernet] Brake cylinder sleeving / P6 rear calipers

[Steve Manwell]

I have also had a recommendation to use Brake and Equipment Warehouse 
for brake cylinder sleeving from a trusted source in the Franklin car 
club.  His contact there is Rob.

I have not tried them yet myself.  I'm sure they are fully capable of 
boring out and sleeving the hydraulic cylinder in a disassembled P6 rear 
caliper, but I don't know if they would want to get into disassembly and 
then rebuilding after sleeving.

Another alternative would be to buy a pair of sleeved and rebuilt rear 
calipers from one of the UK P6 parts vendors such as MGBD, Wadhams or 
Wins.  A US option might be Apple Hydraulic in New York State -- they do 
sleeving and rebuilding of a range of British and other cylinders.

Some other background on this is that a leak from the hydraulic cylinder 
in a P6 rear caliper will leak into the dust cover and eventually leak 
out of that.  (The piston that pushes on the brake pad is mechanical; 
there is no brake fluid behind this piston.) There are also numerous 
brake hose and brake pipe connections associated with the rear calipers, 
so make sure the leak is not from one of these fittings before 
rebuilding the caliper again.
