How to replace the rear breaks on an acura tsx

Jack up the car, use a jack stand and remove the wheel

On the top of the caliper, use a 12mm wrench to remove the top

And bottom

The caliper will slide off, then remove the old brake pads

And replace them with the new ones

This is the piston tool to turn the piston back in. Before you start, take the cover off on the brake fluid reservoir, then use your ratchet to tighten

Insert the matching grooves to the appropriate pattern in the tool

Turn clockwise, slowly

Until its all the way back

Then replace the top and bottom 12mm bolts and your wheel and you're done. Using air tools, this took me 15 min for both sides, start to finish.
