Well it passed it's first MOT with me today :)

after fitting a new handbrake cable as the other one was more stretched than a stretchy thing, rebuilding one of the callipers and welding up a little set of pinholes in the front wheelarch :)

got some advisories though...

front brake imbalance 22% - is this is caused by sticky callipers? - is there a rebuild kit involving SS calliper pistons like there is for midgets?

not written down but the man said the handbrake was very one sided, it's the one we rebuilt not adjusting up properly I think. However, it is just the handbrake that's uneven, the rear brakes are fine. Fortunately the other side was performing like a beast, with a higher brake torque on the handbrake than the footbrake, so overall efficiency is a pass at 23% :)

what's going on there then - as presumably it's adjusted up properly cos the rear brakes work - is it possible to have the handbrake one sided but the footbrake not at the rear?


very pleased with it though. It's going to get some UJs and more valvemaster as a present.
 
Excellent news! Well done.. 8) Nothing like a nice crisp new MOT certificate, although they're now not what they once were...

The handbrake problem is I think almost diagnosing itself.. I think.. The rear brakes & handbrake work through the same assembly, either the brake piston actuates it, or the handbrake actuator pin does, but both bits actuate the same braking parts in the same way, so if your foot brake works but the handbrake doesn't then it can really only be one of two or three things. It could either be due to one of your handbrake lever arms that goes through the caliper body being seized, or a problem with the linkage between the calipers, or a problem with the pins labelled 601922 in THIS diagram. The caliper piston (601918) pushes on the same block (601926) as the handbrake pin (601922), and it is a favourite problem for these pins to get put in incorrectly, as they can lie down in the groove of the rod operating them, instead of standing perpendicular to it.. I know it sounds a bit complicated, but its fairly straightforward once you get your head around it.
 
i'm well chuffed, it could well have been a total blind bought ebay disaster...

not bad for a 1000 pound car , 100 quid or so of bits and half an hour of welding and off we go again!

cheers :)
