I bought an 87 951. Had to replace the front calipers. Noticed the rear calipers had the bleeders on the botton. Could someone tell me if the two larger pistons are closer to the bleeder valves so I can be sure someone didn't just swap the bleeders and the crossover tube.

 

They only fit one way, with "Porsche" out and "Brembo" in. The bleed valves are always on the top.

 

Must have 964/993 calipers on the car, they have the bleeders invertered because the 911s have the calipers mounted forward of the hub. If this is the case, you just need to swap the bleeder screws and the crossover pipe so the caliper is configured correctly for the 944 application.

The smaller piston is on the bottom (leading edge), larger on top (trailing edge).

 

I'll check everything out tommorow. Thanks for the information, looks like I can do something with it.

 

There should be an arrow on the caliper that indicates which way the rotor should rotate through it. If that is correct swap the crossover pipe and bleeder. If it is wrong swap the driver and passenger side calipers.
