Hi Guys I wondered if anyone can help me understand the handbrake adjustment mechanism on the rear calipers of my 1996 Galaxy GLX 1.9 Diesel. Its just failed its MOT on "park brake efficiency" Whats happened is that the rear, passenger side handbrake has seized (somewhwere). I whipped the caliper off thinking that the sliding pins had probably stuck, as this happens all the time on my motorbikes, but although one of the pins was 'sticky' rather than stuck, I don't think it was stuck enough to cause the problem. Looking at where the cable attaches at the back of the caliper, it looks as though there is some sort of screw mechanism (possibly with a ratchet as well) which works the piston forwards as the brakes wear. First question is "am I right so far?" I really would like to strip and grease both sides so the next question is "How?" I have seen what I believe to be a similar system on a Citroen Xantia that I used to have, where you had to screw the piston back to fit new pads, however the piston on the Galaxy doesn't seem to want to turn and I'm afraid to force it. Is there anybody out there who has stripped the handbrake mechanism before? Any help would be appreciated Thanks KK
