What makes a cast iron brake disc Warped?
Cast iron is an alloy of iron and silicon in solution interspersed with particles of carbon. At elevated temperatures, inclusions of carbides begin to form in the matrix. In the case of the brake disk, any uneven deposits – standing proud of the disc surface – become hotter than the surrounding metal.
Why does the inboard brake pad show more wear?
The inboard brake shows more wear than the outboard pad. This happens when the caliper piston is not returning to the rest position due to a worn seal, damage, or corrosion. It can also be caused by a problem with the master cylinder.
When do you use a warped brake disc?
The term “warped brake disc” has been in common use in motor racing for decades. When a driver reports a vibration under hard braking, inexperienced crews, after checking for (and not finding) cracks often attribute the vibration to “warped discs”.
Which is worse front or rear brake wear?
Front versus rear brake wear. Front brake pads and rotors tend to wear faster than rear brakes. Twice as fast in some cases. Is it possible for braking systems made to brake harder on rear brakes than on fronts to even out the wear more? For example, hand brakes on a bicycle can be used by the rider to brake harder on the rear than the front.

What causes brake pads to wear unevenly from left to right?
Here’s my reasoning: Just think of it. Pressure on pads cause pad wear. To get even pressure you have to have the brake fluid flow to the calipers at same rate. So, even if that flow rate is fine, the problems could be faulty pads, warped rotors, bad calipers…
When do front brake pads and rotors wear out?
Front brake pads and rotors tend to wear faster than rear brakes. Twice as fast in some cases. That’s pretty dated information. Used to be true for almost all cars and trucks, but I see many designs from the last 10-15 years (typical family sedans) where the rear brakes are worn out at 50K miles and the fronts last until 80K.
