Sintered brake pad issue

Hi all. I'm new to the forum and was wondering if anyone can help. I just installed a set of Glafer HH sintered pads front/rear in preparation of my first track day. Took it easy for the first 50-60 miles. Yesterday I tried stopping hard to test them and they don't seem to work as well as the factory pads that were on the bike before. What's up, thought these were supposed to make a big difference. Do they need more break-in or more heat to work???

Probably designed for Galfer Rotors, just like a car OEM rotors are better with OEM pads, they make them that way to make the bucks.

Thanks, but from everything I've read, the sintered pads are supposed to be much better than the OEM pads. So, is everyone swapping rotors to match whatever pads they have? Thet can get expensive. Anyone with factory rotors and sintered pads have any opinions?

You need to break sintered pads in just like anything else: use them progressivley harder with adaquate cool down times.

You need to check to make sure that the pads are not dragging due to crap in the piston bores. What can happen when you change pads without properly cleaning pistons and bores is that the pads don't retract a smidge when you let off the brakes, so the pads drag and overheat, forming a glaze on both the pads and the disc.

Check to see if the pads have a shiny finish; if they do, you can break the glaze with a finish block and fine emory paper...then go clean your brake pistons and cylinders and reassemble. Also insure that you have bled the system properly.

I just replaced my brakes with EBC HH pads, and I don't feel that I'm getting full braking power yet. I know it says to give it 250 miles or so. I need to bleed the brake lines too, they seem a little mushy. I've never had to do this when replacing brake pads, but hopefully that fixes everything.

Also, they take a bit to warm up. Until they are warm (actually hot) they won't grab as well as they are designed to.

might as well flush out the old fluid and add new. check the rotor surface, it will take some time for the new pads to break in and match the rotor surface grooves.
