Single to Two Piston on Legacy Brighton 97

Hi all, I have a 1997 Legacy Brighton Wagon. I will be doing my first brake job on it. The parts store had no single piston calipers, so I ended up getting two piston which I'm guessing are from a legacy GT. I have read about compatibility on the brakes and think everything should work out. I also have 15" rims so should not have any clearance isses. Am I missing anything or do you guys have any tips? I bought new rotors as well. Do you guys normally bleed after doing a total brake swap? I know thats personal preference. Just curious. Thanks in advanced for any help. I'll post some pics of the job.

If you bought the calipers loaded with the mounting brackets, and the larger diameter rotors for the legacy 2.5gt, then it should go on fine. If you try to use the rotors meant for a base model legacy, then the pads in the dual piston caliper brackets may overhang the outer edge of the rotor. Brake hoses may also be different between the single and dual piston calipers, it depends on how it mounts at the caliper.

 

Since you are doing both sides, make sure you put the new calipers on the right sides. The bleeder screw should be at the highest point on the caliper so the air bubble that rises to the top of the fluid filling the caliper can be bled out the screw. Any time you open the hydraulic part of the brake system, it must be bled. That's not personal preference. Personal preference bleeding would be if you were just compressing back the calipers as part of a pad replacement.

Thank you, I believe I will be good. I got rotors that corresponded to the calipers they sold me. At least I think I did haha. Now I at least know what to look for if they aren't fitting correctly. Thanks for the reply.
