Dia Compe brake question
Are the MX900 shorter arms than the MX1000?
I have a '83 Schwinn Predator Team 24, and the MX1000 rear brake just barely fits. I have the pads slid up as high as they can go, the wheel as far back in the drop outs as possible and still the brake pads just barely hit the rim. It's as though the arms on the caliper need to be shorter.
Any ideas?
Wanted: Black/White pinstriped California Lite pad (only need frame pad)
Black/White checkered seat cover
Black/White checkered padset (non v-bar style)

Re: Dia Compe brake question
The number 900, and 1000 are based on their reach. I believe MM.

This is with an ACS rear brake (shorter arms)
The wheel is waaaaay back and with a MX1000 the pad is jammed all the way up. At least with the ACS I have some adjustment room.

Hey Matt,
I've had the same fun on some bikes too. Try and research what it came with originally or look at what others have used here in the museum... then you'll know for sure.
