So I had my sled down to do some work. During this work I discovered my brake pads were gone! So I have replaced the rotor and pads. I ordered seals for the brake calipers. I am intimidated to contemplate seal replacement. At a minimum I think I should flush the brake fluid. What kind of brain damage is a caliper seal replacement ? Calipers work, should I be concerned?
It is a 2000 mm, brake line was extended at some point in its life.
thanks

The recommended replacement interval for piston seals (and hose - by the way) is two years.
I'd guess - less than 3% of sleds in the world have had anything other than pads replaced.
If the calipers aren't leaking and I didn't rage with sparks flying from the rotor after chewing through the pads...
I'd ride it for a mile or so without any brake and coast to a stop and check/touch them for no heat. I'd then get them hot (panic stop/ride the brake) and stop/check for leaks while squeezing the lever.
Maybe ride a bit without the brake and check that they cool. Grab a handful in safe conditions for another few miles then I think I'd feel safe.
I've never overhauled a sled caliper but have done plenty others. 14 years of leakage into/past the seals may make for a corroded mess trying to clean sealing surface of the piston.
If the pistons are seeping - I'd definately try to overhaul it before replacing. You'd probably find a used one that isn't leaking for cheaper than the seals.

No it is not leaking, looks dry. Just wore 1 side of the brake pad completely off. the other side not as much. I figure it would be good to bleed the brakes, but have not done that yet. I was going to see what response I got to the seals.
