i dont like sintered on these bikes anyway...just personal preference i guess. sintered pads are for extremely high heat...and with the rotors we have, its basically metal on metal. i cant stand the metal "brushing" sound...along with the risk of the pads causing excessive wear to the rotors. i would much rather buy new pads than have to replace a rotor. Me either. They're a racing application. I doubt I'll ever get the rotors hot enough for sintered pads.
hope you get it straightened out and find some sort of satisfaction. who knows...you could have also just been stuck with a "sub-par" brake pad too...
Any tips on how to R&R the seals, that I've never done before. Uh and I hope I don't, it's time to do the brakes on the F-150 though. Might as well do them all around while I'm doing one. No noise just preventative maintenance since it hauls the 5th wheel and bike.
The seals should be OK. Over time, the lubricant on the seals/pistons dries out or is scraped off. Re-lubing them usually takes care of the problem. Remove the caliper from the rotor. Remove the pads and place a folded shop towel or wood block between the caliper and the pistons.
GENTLY press on the pedal/lever to
SLOWLY push the pistons out about an inch. You don't want the pistons to pop out. Clean the pistons, and around the seals, then apply some silicone grease to them. Don't use anything to clean them that would scratch them! A little brake cleaner and a clean cloth. Push them both back in at the same time. Opening the bleeder valve with your bleeding setup attached will make pushing them back in easy. Now, pump them back out and apply a little brake fluid to the pistons, then push them back in.
I replaced the seals on the rear and re-lubed the front about 6 months ago. They're all still working like new. I think I wasted my time and money replacing the seals.
