Hi
That was a fast response - thanks! Did a bit more research as well -
local Mazda dealership has only ever replaced 1 caliper on a 2000
model 626 and it was 2 days ago! If the caliper is sticking then
they would replace it for £350 inc. (£200 for the caliper). They say
that freeing off a sticking caliper could last from a week to a year
so they only do replacement. My handbrake was out of adjustment due
to a stuck caliper that also meant only braking on one side of that
caliper, and it cost £30 to get it freed - if it's that side stuck
again I'm told it's not worth freeing it off again. I'm waiting for
a manual covering this model to arrive through Amazon but prior to
this my only experience with stuck calipers/pistons is on a
motorbike.Any other info or ideas would be great because this is a
bit expensive!!
Thanks again
Chris
