4 pots - sticking pistons
V3 STi and I'm having a problem with the pistons sticking in the calipers. Car sits all week as I work away from home and over the last month the pistons have stuck twice. I replaced the seals last year and most of the pistons were in vgc but a couple did have spots of corrosion. Easy enough to sort the sticking pistons with G clamps and jumping on the brake pedal
I'm wonerding if I should've put a liberal coating of some sort of grease on the outboard side of the piston seals under the weatherproof rubber boot.
Any thoughts?
My GTB doesn't like standing all week not being used either....

Cheers Bob, I did apply this liberally but wondering if I should've used loads more around the top section of the piston beneath the weatherproof boot. I think if it continues I'll give this a go.

Aha, cheers Alyn. Assumed it was for a liberal lubing of the seal. Out of interest, have you ever seen stainless pistons for the 4 pots - e.g. one's that don't rust
