GS(X)750ESD front caliper strip/rebuild question

[Greenbraes]

I have a set of GS(X)750ESD front calipers that are going onto my GS1000 shortly...I have broken them down for new seal/pistons etc...just one question...is there a trick in removing/replacing the 'axle caliper No 2' the one with the seal..see pic and point 10/11. The axle seems to get held in with suction and I can only imagine it will air lock when I try and rebuild them



any ideas welcome

The trick is don't use too much grease and twist it as you put it in. It can indeed airlock but the twisting gets over it.

Use synthetic brake grease if you have it. It won't go liquidy on you when the brakes get hot.

I have a tub of 'red rubber' grease, this is mentioned a lot on sites about caliper rebuilds, cars and bikes, I believe it is the good when there are seals of any kind involved..I was planning on using this....synthetic caliper grease over here is expensive to say the least....unless someone knows different???...lol

cheers

Sounds like you are good. Honda includes that red grease with their automotive rebuild kits. I think the red rubber is specifically for the piston, but you should be good with that on the pins as well. What is unique about these formulations is that they stay "grease-like" when they get hot. Regular greases liquify when they get hot, which is problem in a place like brakes.
