Did You Know: That Toyota Tundras Have 4 Piston Calipers?

Recently, I did some work on a 2001 Toyota Tundra because it had begun spitting antifreeze through the grille with the force of 1000 agitated llamas.  I swapped out the severely cracked radiator and took it for a test drive to make sure the thermostat and heat were working properly again.  Fortunately, the heating & cooling system worked flawlessly.  Unfortunately, somebody had replaced the brake pedal with a partially deflated water balloon.  It quickly became apparent that braking was not one of this truck’s finest features.  It didn’t grind, but it didn’t stop either.  I ever so gently coasted it back to the garage and pulled the wheel to see what what the rest of the night would look like for me.

2) Hey look! 4 piston calipers and 12.5″ rotors!!  Sweet!
