What specifically does Toyota say to do each year for the brake inspection? I saw a service manual for a 7FGCU that said to pull the wheel cylinders and measure the clearance between the pistons and cylinder bore. However, you must be very careful when taking out cup seals and pistons. My practice is to simply make sure the bore is clean and not pitted, then replace with new seals and pistons, making sure clearance is within specs. Also, when replacing shoes, I always check the wheel cylinders and either rebuild with new seals/pistons or replace assembly. What about you?
