I have a dramatically different feel between the SD and the '86 SDL.

The SD feels classically German with very little modulation and a firm pedal within about 1/2" of travel. It won't go further without quite a bit of force and the vehicle will be hauling itself to a stop very quickly.

The SDL is the exact opposite. The brakes come on very gradually.....starting at about 1/4" and continuing to about 1.25" where they firm up in similar manner as the SD. But, for that extended range, they have a very gradual application and each time I get into the SDL, it's a bit disconcerting.

The SDL uses Textar pads all round and it's been bled more times than I care to count so I'm fairly sure it's not air in the system.......but........can't be 100% sure given the differences between the vehicles.
