hello,
my hope v4 calipers seem to be more or less stuck "on" at the mo, i'm assuming the pistons need lubing... but i have no silicone lube, will normal grease suffice/be ok?
as is always the case i found this out too late and i go away at lunch time tomorrow, if grease is no good then i'll have to run around like a blue bottomed fly in the morning... but if it is ok, then i can do them now! (in the cold garage, brrr)
thanks all
no - normal grease will ruin the seals. Red rubber grease or a bit of brake fluid will do
righto... i have neither of those things, morning madness will ensue... thanks for the top tip!
For a quick fix -
push a single piston out a bit whilst holding the rest in place
rub a little brake fluid on it with an ear bud/Cotton bud
push piston back and pump back out again a few times
repeat for each piston
clean calliper
fit wheel and re centre calliper
set Pistons as per Hope's instructions
hope that helps

i tend to just d o the brake fluid thing
I clamp one caliper - pliers will do lined with a rag to avoid marks- and then pull the lever that way you can extend just one side - free it up and lube it then repeat for the other side
Repeat till both move at same rate when you pull lever.
Pads out for this
Cheers all... hope have recently re done a few of their how to videos so ive absorbed this; [url]
