Replacing calipers

I need to replace my front calipers, I had one seize up on me. I was at the parts store today and they had 2 new (not remans.) Bendix calipers. Same part number with different suffixes. L55640M and L55640PSUV. Does anyone know the diffence between the M and PSUV calipers? Thanks.

You can rebuild a caliper real easy for a fraction of the cost of a new one. I had my left one sieze up on me once. The kit for it was like 10 bucks.

I got mine at NAPA.
They cost about $160, but I took back a pair of junk ones, not even the same type, and the final cost was $30 per side.

rebuilt calipers at Carquest=$15 per side =)

I'm still looking for someone who has experience with the Bendix, or other heavy duty calipers. One caliper can be rebuilt, the other can't, so I'm going the all new route. I can get new Raybestos, TRW, Bendix, and Cardone calipers at a good price. As I said, some of these manufactures list 2 different part numbers. Some say "Severe/Heavy Duty" and some don't. And the prices aren't always different. Any info on the differences would be great.
