Brake piston tool

thingiverse

This is a tool to help easily compress the brake caliper piston on my 2007 Nissan Titan. I had been using a wood block but it would slip around and pinch the piston boot. It sure is nice to be able to design and print a tool in 30 minutes rather than drive to the auto supply store :). It works perfectly. Here are a few tips from my mechanic friends.. Loosen the fluid fill cap and keep an eye on the fluid level, remove excess with a syringe. Compress the piston very slowly, keeps brake fluid from squirting out and allows piston boot to seat well. Lubricate and clean the piston boot with brake fluid before compressing the piston. Turn the wheel fully one way while working on each side for better access to the bolts. Remove rust from torque member where pad retainer seats and apply lubricant to both sides of pad retainer. Update..I added the rear piston tool, a bit smaller. Here are the rear tool parts.. https://www.thingiverse.com/thing:3044658 A360 viewer.. https://a360.co/2vgC4PA
