Overheating Pads (qfm A1rm)

[Equinox]

They required a hell of alot of hard braking before the full surface of the pad had bedded into the disc. I did my normal bedding in procedure and when I pulled over after letting them cool only the middle inch or so of the disc looked good. The rest was still rough. Ended up going on a 200km drive to the mountains to get them properly bedded in. Then I glazed them up again braking normally on the way home.

My experience with the A1RMs has been pretty average - bedded in with the basic 10x 100km/h-0 stops then took them up to Mallala. Mallala is notoriously hard on brakes with hairpins at the end of two straights. First lap fine. lap two stopping from 180 into the hairpin brakes faded to zero whilst still going 80+, so ended up deep into the gravel.

Perhaps they needed more bedding, as during the rest of the day they **just** held up but still got really soft and felt very unreliable after lap 2. Having run the Ferodo DS2500 before they are (in my limited and personal opinion) *not* comparable - I've never had any problems with the ferodos even with much less bedding in.

Second trip to Mallala same thing happened - first outing into the gravel with on lap 2 zero brakes. Same barely adequate but not catastrophic performance for the rest of the day. by the end of that day (so after ~40 laps) they had 0.1% left. I've now put Project Mu HC16-03s on which stop it like a brick wall, but are not drivable on the street at all due to noise. Once they're gone will try the HC+ and see if they're a good middle ground.

I still have them on the rears and have easily 80% left.

I also feel there's a bit of spin around the A1RMs, but then

a) they're half the price of the DS2500 for a couple of reasons, including perhaps better value but also lower level of performance

b) no-one on an internet really knows your specific application and what you're going to be doing with them, so really it's buyer beware.

Thanks for your help guys. Gonna try some HC+ pads.

Will I demolish RDA rotors with HC+ pads? Should I 'invest' in some SCR rotors or just give the RDAs a go?

I had Project Mu type NR pads matched with SCR rotors.

The NR pads were garbage for street driving as they needed warming up to actually stop.

Changed to A1RM and i think are perfect for the street with a bit of hard braking. Great initial bite with no fade with long hard braking. Hardly any noise.

Used them at Oran Park and were great for about 5 laps, then started to shudder pretty bad and had to bring it in.

Ill keep using the A1RMs for street but might try the Competition ones next track day.

So Jetpilots description of the A1RM pads is spot on. Good for street and light track work.

Yeah that is fair, although "light" track work doesn't really happen on circuits. Motorkhana/autocross/hillclimbs are fine as there's generally little high-speed braking, but any day at a circuit track that includes 2+ laps with braking from faster than 150km/h is probably more than "light" unless you take it really easy - and who does!?
