New caliper brake pressure mystery
Posted: Mon Dec 24, 2012 11:53 am
A happy Christmas question for everybody:
I have what was a fully functioning mk2 golf rear disk conversion on my GTX. All was fine, until having replaced the old calipers with new ones I couldn't get any pressure in the system after bleeding.
Assuming it was the master cylinder (it is a 22mm bore), but not sure, I took it to the garage.
They confirmed it was the MC and replaced it.
Now despite bleeding it many times, manually and back bleeding, they still can't get pressure in the system!
Their last resort was to remove the pressure regulators going to the back brakes.
Before closing for Christmas this morning they called me to say its not ready yet, so either the regulator trick didn't work or they've not tried it yet.
Anyway, I'm stumped for ideas, as are they. Other than the new calipers being shot (they aren't leaking any fluid though) I can't work out what could be wrong!
Does anyone have any suggestions? I've got a week over Christmas to ponder it.
Thanks and merry Christmas!
