Replacement brake rotors are loose

[Tom La Rocque]

Mazda 5 – 2009 front rotors and pads

Should replacement brake rotors be loose. Or should I ask ‘can’ they be loose upon replacement. They are basically wobbly, even with the caliper and new pads installed. This is the first time I’ve seen something like this. Usually they are like a compression fit and are snug.

Thanks,

Tom

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.

Thanks for the advice. The wheels and rotor are a tight fit with the lug nuts tightened correctly.

That is a fix.

The pads and caliper hold the rotor on pretty well. But they can move a little on the opposite end. When you bolt the wheel back on, it’ll compress the rotor and give a solid fit. If you can almost remove the rotor off a lug or two with everything installed, I’d be measuring the rotor specs with OEM rotor specs. But if the opposite end of the rotor (from caliper and pads) moves a 2-3 inches maximum, you should be fine.
