Are front or rear rotors more important?
Front brakes wear quicker than rear brakes because they do most of the stopping. Front brake rotors are usually vented and have fins sandwiched between the two surface, while rear rotors are usually solid metal discs.
Can you change brake pads and not rotors?
A: Unless the rotors are worn beyond the mandatory discard thickness, we prefer to replace the pads only. Not only does this obviously save money, but time. New pads must be burnished into new rotors before the best braking performance is achieved.
Why do brake rotors need to be replaced?
Brake rotors are expected to wear down in the shape of brake pads, and these indentations can often be resurfaced away (until the rotor gets too thin and must be replaced). Grooves can also be caused by foreign objects under the brake pads, corrosion, or by softer metal in the rotors than on the brake pads.
Which is more important front or rear rotors?
In most cars, the rear rotors are the easist to replace, but you have AWD, so I guess that the replacement will be as much work for you as the front rotors would be. But if they don’t seem as important as the front rotors, be assured they are worth the effort and extra cost. Rear brakes need to work in concert with the front brakes.
Why do cars not turn their rotors anymore?
Second, as mentioned turning rotors makes them thinner making them more suseptable to warping. And third and more importantly, when the rotor is turned there’s no way that the proper finish will machined onto the rotor so the brake pads properly embed into the rotor. This then causes brake noise. That’s why nobody turns rotors anymore.
Why do my brake rotors keep warping?
The most common cause of brake rotor warping is excessive heat buildup caused by: Glazing from brake pad material – Pieces of brake pad material can transfer onto the rotor. Rotors that are too thin to dissipate heat – Rotors wear thin due to regular use (and resurfacing during brake service).
