Thanks again for all the replies.
I have fixed the brakes (well mostly).
I bled them out again & an absolute load of air came out of both front calipers, so they obviously didn't know what they were doing when bleeding them out. Now they had been bled again the brake delay has gone.
I pulled the rubber boots off both calipers & found something potentially disturbing, the spring, that clips around the handbrake rod/ lever to push it off, is missing on the RH caliper. Is that a problem? The mechanism appears to all work as it should.
While I had the boots off I put some more greese in there, although it was quite good anyway.
Also the handbrake has auto adjusted up on the RH caliper, but not the LH one, so its pulling the left cable more than the right one. I followed the instructions above to adjust the handbrake. Any suggestions why or what else to do?
