My Duster currently has an 11.75 Slider disk setup in the front and 10x2.5" stock 74 drums in the rear, 15/16" master cylinder. Calipers are '80 Volare phenolic piston calipers with the 2.75" bore.

When I first did the conversion, it had some not great shape 10.87" rotors on the front and some semi-metallic pads. Didn't stop all that great...

I upgraded to the 11.75" brakes last year and threw on a new set of Wagner Thermoquiet pads. I am totally unable to lock the 225/60-15 BFG G-force sport tires on the front. It's adequate for tooling around town, and if you do a couple very hard stops, they start to work a bit, but they are absolutely nothing like the similarly sized brakes on my '04 Colorado or '12 Cruze which are phenomenal.

The brakes are fully bled with fresh synthetic Dot3/Dot4 when I put on the new master cylinder. The car has an adjustable prop valve in the rear line, and the pressure is dropped nearly all the way. It's not so hard to lock the rear, complete with the 20 year old shoes and likely original chrysler drums...I can get a screech out of the rears on almost any stop.

This is what makes me think it's the pad mu (friction coefficient)...I have driven 1000 miles since the brakes were installed, and I can still make out the cross-hatch on the brake plates.

Is there a set of brake pads that is street friendly (don't need to warm up forever), but have a high friction coefficient and hopefully won't squeal too much? I haven't seen much of a selection.
