Dear Rich and Frank,
That did the job, thank you very much for your advise and en
encouragement.
When I got the main brake calipers loose (pads and mounting
bolts off) as you mentioned I could get the whole assembly
forward a bit and then I saw that even though I had removed
the bolts and holding U from the handbrake caliper it was
still firmly attached to the main caliper. I got a screw
driver in there and levered them apart and the then the
handbrake caliper slide back and round (as in the manual)
and I worked the main caliper out through the front. That pa
part completed!
Good work, Neil - removing the rear calipers is not a walk in the park…
I should also have mentioned that the brake fluid line should be capped at
removal - to prevent air and dirt ingress, it will ease the airing after
reassembly. Also, check the bores in the piston for signs of pitting
corrosion - if the bores are not smooth, downstream problems will occur. To
some extent the bores may be lapped - but extensive bore pitting may require
more extensive work, like professional resleeving - or caliper
replacement…
After reassembly, the pistons should be pushed fully in - again too reduce
airing the brakes, and attend to the retracting forks on the handbrake, they
are supposed to be replaced when worn hand brake pads are replace. And
refitting is fairly straight forward - the reversal of the removal, but
working by feel…

The main caliper as suspected is a mess. Dust covers just frag
fragmented into pieces and the pistons are very rusty. A comp
complete rebuild with new pistons and seals.
I have to say I am already dreading putting that U shaped ho
holder back. I hope I can assemble it before sliding it up to
to the top as to get the U into place when I cannot see the ho
holes will be impossible!-----Original Message-----
