rear calipers

i'm having difficulty getting the brakes to work properly on my PH2 twinny. after stripping the rears down to exercise them a bit, the N/S wound back in nice and smoothly with what seemed like a normal amount of resistence, however the O/S took a mammoth effort to wind in and i ended up having to use a spanner as a lever on the rewind tool arm to do it... is this normal and therefore the N/S could do with replacement or am i right in thinking that the stiff one its Ca'putt?

Also does the rears have any effect on the fronts efficiency? via back pressure from the compensator etc?

Assuming that you dealt with both calipers the same (i.e. you didn't have the hose clamped for the second caliper) then winding-back stiffness is not good. It may be worth a rebuild if you fancy buying the kit.. but when they get tooooo shonky it may be better value to go for a rebuilt caliper (basically all new parts inside a cleaned up like new old caliper body)... aboot 100 exchange.

The rears don't affect the front, if they're not working. The compensator determines how much force is applied to each end but once the brakes are on, each circuit is independent. If one caliper (or one end of the car) has shonky calipers, the other end is isolated and doesn't know about it.

Just had the same problem, failing the MOT as a result. If it doesn't want to wind in and pop out then its probably more than just seals etc that you get in rebuild kits.
I had a second hand caliper from AutoLusso. Not reconditioned but very clearly happier than the one I took off. 40

Its above the rear second to last exhaust box, inboard rubber hangar, on the Lh side of car (close to subframe x-member) if I remember correctly. Its a nightmare to get off, it'll be a struggle to undo the 4 brake pipes that are positioned on its upper surface.
