crossed drilled rotors?

Question

i have warped crossed drilled rotors i need to cut. who can cut these rotors? ive had them for a month and they got warped. whats up with that?

Answer 1

several problems can exist.One you got rotors hot and hit a water spot that caused them to cool rapidly.second cause could be that when you install wheels you did not torque the wheel in proper sequence.Third your calipers could be dragging not releasing all the way.Fourth you do not have proper brake adjustment in rear causing the front to do all the work.If you have just installed a new or re man master cylinder check to make sure the brake pedal to master cylinder rod is not to long/ applying the brake.After making sure this is not any of the problems you could have a set of defective rotors.Also make sure that air is able to circulate around the brake area.Such as body kits blocking air to the rotors

Answer 2

Cross drilled rotors are weaker than standard rotors and, with less metal to absorb the heat, they'll heat up faster. Consequently, they are more prone to warping than an otherwise identical rotor without the holes. My guess is that you bought a set of cross drilled rotors that were not actually designed for cross drilling but simply a case where a supplier bought standard, off the shelf rotors and put them on a drill - or possibly a set of cheapo made-in-China rotors that were not very good in the first place. Or sometimes both.

For anything besides motorcycles (where they are simply a weight saving measure and the rotors are already very large in proportion to the vehicle weight), cross drilling the rotors is not very good for performance or durability. I'd say just replace them with good quality rotors - preferably WITHOUT the crossdrilling.

Any machine shop, and many auto parts stores turn rotors. They turn just like any other rotor. The major cause of rotor warpage is improper torque on the wheel nuts. Most cars are supposed to be around 50 to 70 foot pounds, pickup trucks 90 to 100 foot pounds. If they aren't torqued correctly it puts an odd amount of pressure on different places on the rotor and causes them to try to conform to that shape. If you take your car to a tire shop for replacement of the tires, tell them not to run the wheel nuts up with the gun. Most times they hammer them on with the gun and by the time they are checked for torque, the nut is already too tight. The wrench might click, but it hasn't tightened anything.

hi , you need to purchase Cordless Drills . It performs drilling and using projects conveniently no be counted the place they're needed. no be counted in case you're purely entering into your first condominium, or you're a pro builder, a sturdy cordless drill is between the main versatile equipment you have got around the homestead, storage or workshop. The extra torque a drill has, the extra appropriate it is going to drill into extra sturdy surfaces.

Answer 5

You should go back to where you got them from and either get a refund or exchange them for new ones. And don't ride on the brakes so much!!

hard driving or defective brake system
