This is a set of OEM pads from Sram Rival AXS discs. They’re on a Giant Revolt Advanced.
​
I was descending some “technical” single track when I heard a pop and then scraping come from my front brake. I was able to finish the ride with a lot of scraping noises from the front, but still effective braking. It looks like the “clip” that holds the pads together must have snagged on the rotor and gotten partially torn off. It settled in a position where it wasn’t riding on the braking surface which is lucky because I think that’s why I was able to continue riding to get back to the car.
​
I’m just wondering, is this thing that broke basically the return spring for the whole caliper, or is it just for holding the pads roughly in position? I was able to trim it and shape it so that I can reassemble but I’ve been holding off on riding for now. I’m going to order a new set of pads either way but I’m just trying to understand (1) how these calipers work and (2) to what degree I should avoid riding this bike.
​
Thanks!

Edit: Also, if you have an opinion on what pads to get for this caliper I would love to hear that.

That pad on the right looks pretty thin – and that probably caused your issue in that it got so thin that the spring got caught on the rotor so if you straighten it and put it back together it will probably happen again.
The only solution is new ones.
I like discobrakes.com – I have the Kevlar ones and they’re great. They have all different shapes – just get the ones that match yours.

The clip is a return spring as well as pad guide. You got lucky. Not sure why is got caught but I’d guess it’d happen again if you tried to ride it. New pad day!

The stock rival organic pads are trash. I had lots of issues with them gunking up my calipers, which accelerated issues like rotor rub. I’ve had much better luck with 3p sintered pads. Kogel ones were OK, but I put on a pair of swiss stop exotherm pads last season and they are fantastic. The cooling fins make a huge difference on long descents.

This is the kind of reason to keep old parts, in this case the pad springs, and even usable but worn pads.
If you want to be riding before you have new pads then I suggest that you swap the current rear pads to the front, and install these on the rear. Then use the rear brake as sparingly as possible.
