[Closed] Formula Ones pads not fitting

[quote=chvck ]I'm buying cheap pads from uberbike so maybe the tolerances on pad thickness are a bit out?
This. I've seen lots of non-Formula pads that were just too thick. Either grind them away a bit before fitting or buy the (expensive) Formula pads.

This is one of the main reasons we only sell genuine pads-the amount of time it can take to make aftermarket ones fit!
Often they have too much material on them & need grinding back before fitting & often don't come with the springs that can get trapped & wrecked if you wear them really low.
I know there's still a huge difference in price, just saves time & hassle in the workshop as much as anything else.

OK thanks guys, sounds like it is that then! The uberbike ones do come with springs at least, as I'm cheap I'll just keep getting those and grind them down a bit!

I find emery cloth on a flat workbench & rub the pads onto it the most effective way & most likely to keep the pad flat as well & not wear it on a strange angle.

I had to file down my superstar pads slightly to get them to not foul the rotor with my Formula The Ones.

Never had a problem with Superstar pads in my 4 sets of The Ones (or the 4 sets of Oros that predated them). Uberbike ones I suspect come from the same factory... Are you absolutely sure the pistons are staying fully back? It's fairly common for brakes to push back fine but then move slightly back out (normally caused by a little pressure in the bellows)

Was having the same problem,used a file to rub the material away fit snug now.

I've even found Swiss stops a snug fit on my r1s.

Chvck, do you use the pad spacer that came with the brakes to push the pistons in with? I use them and pull the lever a few times before fitting new Aztec pads. I run Hope sawtooth floaters and they are shall we say a very snug fit. Seems to work for me. Are the pistons sticking slightly? Aztec sintered - brilliant pads 8)

Pretty sure the pistons are right out, I do use the pad spacer. They don't feel sticky either, I'll just file them down a touch 🙂

Northwind + 1. My old avids on the other hand....

I'm with Northwind too. Been using Superstar pads in my Ones (and RX's) for yonks now with no issues whatsoever.

Have you let enough brake fluid out? Open the bleed port a 'tad' then push the pistons back fully. If any fluid comes out, the system is over filled. You are welcome.

It's not just pushing them right out (and the pad spacer probably doesn't, but should get very close at least)- it's also that they can creep back out once you remove the spacer. Not normally a problem with Ones to be fair as they have a pretty open diaphragm, but not impossible.

I've been running Alligator pads in my R1s, RXs and The Ones for ages, no issues with them. Try them for an aftermarket one. Plenty grippy enough and last ages too. Can change a pair in under a minute, useful in races like Keilder!

Spacer does not push the pistons far enough back sometimes in my experience. As Lord Felcham says bleed a little fluid out carefully while pushing the pistons all the way back in.

Yup, every time - I then always end up doing a full bleed just to see if it helps, never does! I'll try pushing pistons back more but will probably just file down the pads, it isn't much hassle!

I had the same problem with formula the ones 2011 models, they tolerance is very little between the pads and rotor. Try servicing ur callipers and re bleeding I also ended up buying a new piston kit for the lever from silverfish and now they feel new again.

Also I feel formula pads r not lasting as long as they use too, anyone else noticed?

I had same prob with my formulas every time I put new pads in, someone once loaned me one of those park piston pusher tools, which is like a thick screwdriver/ spatula and it really did the trick, much better than a screwdriver or a spatula, suggest worth investing in if you have formulas.

i aint got around to changing out my original pads yet but been looking at a sintered set from superstar.... anyone think they are better than the std ones?

also do you have to bleed the brakes EVERY time you change the pads? or is that just a personal thing?

thanks

Bleed the brakes when you change the bike, NOT the pads!

If you're having to let fluid out to fit new pads, it's because they were bled wrong.

I don't, no fluid comes out - I just always try it because I figure there's nothing to lose, they can't fit any worse!

Iv always bought formula pads but at £23 a pack I will be trying SS from now on
