Oiwa Garage Tech Note
"This is the front brake rotor set. Fit fresh pads with the rotors and bed them together with moderate stops. Clean the hub face so the rotor sits flat and does not introduce runout."
Frequently Asked Questions
Should I replace pads with the rotors?
Yes. Fresh pads and rotors bed together for the best braking and even wear.
Do I do both sides?
Yes. Rotors are replaced per axle so the truck brakes straight.
How do I know the rotors are done?
A pulsing pedal or steering shudder when braking, a lip worn at the rotor edge, deep grooves, or rust damage all mean the rotors are due. Measure the thickness against spec if in doubt.
