Metallic, Resin....

Best of both worlds. But this can backfire as you will also have the worst of both worlds.

Brake feel - Compared to metallic, the resin pads are soft and can give a more spongy feel. The metal in metallic makes a more rigid pad that gives more of an on/off feel. Although not a huge difference, you could achieve an in-between feel by having one of each.

Sticky piston syndrome - On some calipers one piston will always work its way out farther than the other causing misalignment. The more free piston gets the resin as it will react as needed to compensate for the rapid wearing resin. The sticky piston gets the slower wearing metallic.

Harmonic vibration - The different resins have different weight. The pads will not vibrate at the same frequency. Possible canceling out each others tendency to vibrate.

YMMV

But I'd have to buy twice as many sets. :bang:

This was one of the voodoo/black magic ways of making Avid Juicy/Elixir brakes from not producing the turkey warble that most experienced.
 
Shimano metallics have always squealed for me. So I pulled the metallics off my new Shimano brakes (to replace SRAM level ultimates, but that's another thread) and put on resin, then looking at the brand new metal pads in my parts bin over the last year going un-used, I figured what the heck and went for half and half on the front a few weeks ago to see what would happen....works great. No squeal and braking feels more powerful. To make it even a bit more weird, the metal pad has the heat dissipation fins and the resin doesn't.

Yes, let's ask a personal opinion question on a mountain bike forum, as those questions are always super productive.:rolleyes:

What is the best ................... lube?, chain?, dropper post?, tires?, tires for SoCal, LOL?, stem length?, travel?, bike?, bike brand? I know ... did I leave anything out?

All above referenced threads are exactly the same ... as in personal experience and personal opinion. But you already knew that.

I'm guilty of this... so just to shift the paradigm a bit... I stumbled onto this guys youtube channel during my daily, mobility strecthing and youtube session. At first I was slightly annoyed by this guys video style but it ends up pretty endearing.

In this vid he goes over a technique of evening out brake caliper pistons and providing some lubrication to the piston seals. Initially I was very dubious of his methods for several reasons. Turns out, I've done this on two bikes that have come through my garage (one being mine) with sorta so/so lever feel and brake consistency and this trick has worked great. This isn't an end all be all to brake issues, but it does seem to fix those stubborn brakes that feel not quite right even after a fresh bleed and new pads. This trick was especially helpful for a recent set of XTs and a set of guide r's that were performing decently but just didn't feel confidence inspiring and the brake rub wasn't quite perfect.

YMMV.
 
Used to think I had to have resin compound pads. I tried metallic again and realized that, on my current bikes, metallic stops great, lasts long and doesn’t ruin rotors appreciably faster.

Occasionally knocking back the pad glaze with emery cloth and hitting the rotor with Scotchbrite pad keeps mine and hers quiet.
