Ok, so before you get too excited these are the front calipers from my VW Campervan project
I've had them shot blasted and Electro plated by my friendly fabricator chappy.
I've got all new seals and pistons from Bigg Reds Brakes.
The seals come with a sachet of Silicone grease. the question is where is the grease supposed to be applied;
A) around the piston rubber seal before fitting to protect the recess from corrosion.
B) liberally around the piston outside the piston seal.
C) inside the dust seal before fitting
D) All of the above

I dunno mate, you tried youtube'ing it?

....or don't bother fitting them, they don't go fast enough for brakes :hide:

There are a million n one videos:nenau
The first one i watched showed using 3 in 1 oil to lube everything up.
I'm thinking D) as the silicone grease keeps its grease state at high temperatures, so protecting the exposed piston from MOISTure:augie

 

[terranosaurusdoug]

Is it high temp or some special grade? It might be just for assembly to help things along, so you don't damage the seals. I'm not too familiar with brake calipers I'm afraid, does the brake fluid not lube the piston bore?

You do not want to be putting anything on the brake fluid side of the piston other than pure brake fluid, the silicon grease must only be applied to any exposed piston and inside the dust seal, Rick

I agree with Rick entirely here.:thumb2
Also the Pistons can be fiddley to put in with the dust seal and retaining wire so don't be too liberal with the grease to start with. Keep it clean.
Nice refurb by the way.
I see you've a tin of Caliper Black in the pic. With the finish you've achieved on the refurbished calipers, can't you leave them as they are?:nenau

I can see an empty jd bottle. I don't think he really cares:lol

Silicone lubricant is to protect the seals.

The silicone lubricant is used to protect the piston seal from damage as you insert the piston into the caliper body.
Use sparingly, it will not attack the seals any excess will not affect the brake fluid.

I stand corrected with respect, I was always told never to contaminate brake fluid with anything, Rick

Thanks Guys:thumb2
All have confirmed what i was thinking.
Tomorrow is assembly day, after JD Single Barell day, JD Fire day and a Dowes Port evening.......
A couple of coats of caliper paint and a set of mintex pads..

Panic not this is just a practice for the Troll calipers:clap

Just waiting for the new pads
