Do you have to remove the axle nut to remove the rotor?
It looks as though the axle nut and rotor screws all need to be removed in order to replace the rotor. No, you do not need to remove the axle nut.
Can a brake rotor be loose?
The rotor will wobble with the wheel off of the car, once the wheel goes on the lug nuts will squeeze the rotor between the back of the rim and the wheel hub. If the rotor is wobbly withe the wheel fully torqued, then something is not installed correctly.
Do you really need brake rotor screws?
Set screws are put on during manufacture to keep the disc in place on the assembly line. However, once the car rolls off the line, they are completely useless. People will say the screw is necessary for the brake disc to stay in place while the vehicle is moving.
Do you need rotor retaining screws?
No need to replace those screw(s). They are only there to keep the rotor in place during assembly so that in won’t fall off until you have the wheel in place and tightened which is what actually holds the rotor.
Why are the rotors on my Toyota Sienna Warped?
Brake pads wouldn’t generate much braking force on a perfectly smooth and dense steel rotor. It’s the transfer of pad material into nanopores that creates friction and stopping power. It’s like the brake pad (in tiny pieces) looking back at the original brake pad.
What causes steering wheel to pulsate in Toyota Sienna?
If that material permeates the rotor unevenly, or you get spots of build up on the surface (patches – that’s the thickness variation – TV) or you get iron carbonate nodules (hot spots), you get the feeling of pulsation in the steering wheel. It can also happen when the pad’s “imprint” on the rotor.
What kind of pads does a Toyota Sienna use?
Toyota sells a mix of semi-metallic and ceramic pads – both on the car from the factory, and thru their parts department. The big trick is the true definition. Pads today are a wild mix of materials. A semi-metallic can contain ‘ceramic’ base materials, and ceramic pads can contain metallic particles.
Why do I have runout on my rotors?
Ceramic pads transfer friction material to the rotor to increase friction and braking power. When a rotor is installed with runout, the material is transferred unevenly resulting in brake judder.
