Brake pad materials - ratings/selection
Brake pad materials - ratings/selection
(OP)
Sorry, my Google-fu is filing me today.
I thought there were some ratings for brake pads, in terms of temperature resistance/behavior, effectiveness /grip hot versus cold.
Most of the "info" I can find is subjective and/or inconsistent.
help?

When doing a conversion, how do you figure out what material to start with?
(for example, using a standard assembly in a different vehicle)
thanks

If the pads are low friction, with modern boosted (over boosted) systems it's still relatively easy to press hard enough to lock wheels.
A lot depends on what you are prepared to compromise for what, ie Noise/squeal, black dust on rims, fade, life, rotor wear, cold vs hot performance.
Personally I always looked for fade resistance and better hot performance over everything else, then reasonably quiet, but then I'm a bit of a lunatic when I find a nice quiet winding road or mountain pass. I also tend to tow heavy loads at times.
I still prefer sintered copper/ceramic pads with the knowledge they may squeal a little and will need a warm up, ie left foot brake and drive slow from a cold start for the first 100 yards or so.

If the duty is quite different then you need to consider energy over time as well.

Eventually, I should probably go with disks up front instead of the ancient drums.
Yes, this is the bastard Corvair I've asked about in the past- rear MacPherson struts, 3.8 Buick, etc.

I guess your using the drive train out of a front wheel drive V6, installed in the rear, brakes and all.

I'm not saying it doesn't vary, I'm not saying nobody makes a 0.6 pad. But we don't fit them. Change your mechanical or hydraulic advantage.
