GQ Brake Pistons.. now with video
Hi Guys,
I drove home and jumped out of the Trol after hearing the brakes squeeling and the rims were so hot I could not touch them the brakes must of been draging on the discs.
I guess your not supose to pump the brake pelad when there are no pads in there as i done that and the piston poped out.Should I be able to move the piston in and out by hand ( I tried the other side one and I cant ).
If the piston is so tight how does it retract.
Is there some way to adjust the amount of drag on the disc, the Greggory manual talks of using a spring type tool to check the tension and says to adjust the drag...
Here are pics of the parts. Are they stuffed. Am I better of finding some more from a wrecker maby..
Any advice much apreciated.
Ray

I have just put new seal kits through my callipers and the pistons took a little bit of playing around and some high temp grease but got them in by hand. Don't know anything about adjusting the drag sorry

Supacheap/repco/autobarn have a bolt in replacement unit for $50. (for a GQ)
I have located a bloke in cairns selling them for $22 each. at this price, it is not worth the $20 for the rebuild kit.

I phoned Nissan and they wanted $125 for seal kit both sides, and $154 per piston.
Repco was $18 per side for seal kit and they said pistons wrer not listed at all...
Might take them into local brake joint and see what they say.
Will go into Super cheap too.
Cheers Ray
PS. see what happens I might hit you up for more details on the pistons Werafa.

RIP - valued member and true gentleman of this forum that will be missed by many!
the usual grease for brake components used to be rubber grease. I've never used HT grease on rubber brake components.

mate it looks like you have simply melted the caliper seal to the piston.
try soaking the piston in gasket stripper or something, thinners take ya pick.
just remember to be sure it's totaly clean of anything once cleaned up.
use rubber grease only going back in.
FYI, your not supposed to use anything but rubber grease and brake fluid to be technical you be the judge.

Thats probably right to mate as the rim caliper and even the tyre were incredibly hot. Any ideas what caused them to get hot.
