Brakes Replaced

IMO If the seal for the piston is fine with no nicks or tears don't touch it. As they other have said Prelude brakes need attention every year. Once you are on top of them it only takes an hour to break everything down, clean, re-grease and put back together.

Get some red rubber grease and move back the seal on the piston and grease the outside of the piston (Piston Boot seal). How much of this piston you grease will depend on how much your pads are worn. However if you look at your brakes every 6 months then over time you will grease alot of the piston.

So 3 of my pistons had no nicks or tears but had seized, do I cut the rubber seal and put the grease inside?

Sorry, are we talking caliper pistons or slider pins?

Slider pins

If the slider pins are stuck fast you need to get them out anyway you can, ideally without harming the boots. In the past I have had to use heat to expand the metal of the carriers to get the pins out (this destroyed the boots). They just pull out.

If you get the pins out without damaging the boots try and scrape any of the crap out of the slider pin barrel. I find emery paper wrapped round a pen a good way of getting the jobby out. Sand any of the guff off the pins and grease lightly and put back together again. The sliders should move freely.

If the boots have even the smallest nick or tear they need replaced or they seize up again.

Are the boots easy enough to replace?

Easy. They just pull off. Once you get the new boot attached to the carrier, pushing the pin in seats the boot properly on both ends.

Oh ok...I didn't know they came off.
