Disc Brake pads

cirian75

I have my 2016 Giant defy disc

runs the TRP Spyres and uses the common as muck Shimano M515-M525 size pads

The stock ones are a complete pile of crap and I have ID'd the discs Giant installed as a really old Avid model

so a set of Shimano RT76 discs have been bought, now just need new pads, not letting the TRP ones anywhere near these.

requirements, decent performing quiet pads, my commute is almost all flat so super long life is not a requirement and will be riding mostly dry with occasional rain.

Was looking at fully sintered, but it looks like resin/Kevlar/organic my be my solution

opinions and ideas please ?

If long life isn't a requirement then keep away from sintered. Less powerful braking and more prone to squealing.

Organic/standard pads are probably your best bet although I've always been a fan of Superstar kevlar on my mtb. Mid point braking power and seem to last a while. Not had to change the pads on my roadie yet so am keen to hear views

I've been using a old MTB as my short commute to work for a few years now, so about 5k (miles) pads still have life, cheap organics.

for road don't get as gritty etc to wear pads though.

cirian75

ok, so which organic/resin/kevlars do you recommend?

Just ordered 4 x organic from Superstar. £18 all in I think for XTR ones (for use with Juin Tech)

I may have got confuddled here but I always thought sintered pads were the better option.

Thats what I've run for years on my Heckler and never had any issues with noise.

Just fitted some Aztec organic pads to my Spyres. They seem OK so far. It got pretty wet for a time on Saturday on my ride and they weren't too noisy.

Did you find the stock pads to be bad?

The stock pads on my Spyres were fine until I went out on a filthy ride in the wet (the bike & I came back from the 40km ride looking like I'd been spray-painted with mud from head to foot) - that single ride tore through the remaining 2½mm of pad right back to the back plate (the rest of the pad had taken 5000km to wear off)

I replaced them with Shimano M05 pads which are showing no imminent signs of wear 4500km on...

The discs are still original - they work, they haven't reached the wear limit yet - so no rush to replace.

This is on a 2015 Giant Revolt with a 95kg rider in a hilly area.

Not especially. A bit noisy in the wet but otherwise OK.

You are, the materials have different benefits and weaknesses, neither is better.

I'd certainly stick with either plain organic or Kevlar for a bike used on the road, my commuter did over 6000miles on a pair bought used in the callipers, the front pads lasted 'just' 4000 miles before I changed them.
