Re: Dimpled and grooved ticking noise

No point, they're always going to be noisy. You'll be able to feel the grooves in the pedal action when braking hard too, as they machine your pads down. Yup, standard run in procedure to transfer some pad material on to the discs.

Do drilled discs make noise?

You will hear a little extra noise from the grooves. The brembo max ones aren't too bad, I had some tarox grooved discs that sounded like a washing machine.

Are slotted and drilled rotors loud?

They are definitely a little noisier than the smooth stock discs, which is obvious due to the surface being less even. However it is still rather discreet and I can't see how anyone would be bothered by this. My new Performance Friction BBK however (slotted discs) has a turbine-like sound when I brake.

Are drilled brake discs worth it?

Drilled discs can cool down quicker than standard discs due to the increase in surface area. They also allow for quick expulsion of the gases, meaning you won't experience brake fade as quickly as you would on standard discs.

Are drilled and grooved discs better?

Slots or grooves in the surface of the disc allow gases to escape, and there are additional benefits. The 'scraping' action introduced by the slots can clean the pad, and the edges of the groves increase friction, albeit at the expense of pad wear. And finally, like drilled discs, they look pretty awesome.

Are grooved discs worth it?

Grooved discs offer better cleaning of the disc from the brake pad dust and that's it more or less. I would probably go for a good quality simple disc if you have already upgraded the pad.

Is it worth getting drilled and slotted rotors?

Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.

Do drilled rotors last longer?

Drilled rotors are also a poor choice for race cars. They cannot withstand repeated heat and cool cycles very well, and will fail sooner rather than later as a result. Drilled brake rotors are fine for general use in street vehicles.

Are drilled and slotted rotors better on a truck?

Since cross-drilled and slotted rotors are better at keeping brake dust from accumulating on the rotor, that means that there's more brake dust making it's way to the wheels. You'll spend more time cleaning the wheels on a vehicle with drilled or slotted rotors than one without.

Are drilled rotors better than solid?

Drilled or slotted rotors are great for performance cars. If you have a performance car, avoid solid rotors. Solid rotors won't maximize your car's braking performance. Instead, get drilled rotors, slotted rotors, or both drilled and slotted rotors.

Why do drilled and slotted rotors squeak?

Brake squeal is caused by high-frequency vibration between the brake pads, rotors, and calipers. It could be possible of missing springs or anti-rattle clips that should be on the caliper or pad, loose fittings of brake pads in the caliper, improper tightening of lug nuts, or calipers upon installation.

What direction do drilled and slotted rotors go?

Slotted rotors

For rotors with slots machined in the same direction as the internal cooling vanes, the slots should lean toward the back of the car. For rotors with slots machined in the opposite direction as the internal cooling vanes, the slots should lean toward the front of the car.

Are grooved discs noisy?

Guest. It's normal for them to make a noise when you're braking - the harder you brake the louder it gets. Mine have never made any noise unless I've been braking though.

What are vented brake rotors?

Vented brake rotor designs are thicker CNC-machined cast-iron discs that have a hollow vent or channel between the front and rear rotor surfaces. This allows for enhanced heat dissipation. Vented discs usually appear at the front.

Can drilled rotors be resurfaced?

Can You Resurface Drilled & Slotted Rotors? It is possible to machine or cut a drilled & slotted rotor. To do so, the brake lathe should be set to its slowest setting. Whenever brake pads are replaced, the rotors should also be replaced or resurfaced to allow the new pads to be properly bedded.

What is the point of drilled rotors?

Drilled-slotted rotor design offers the driver an advantage with a few side effects. Furthermore, the holes drilled provide a better cooling effect from the heat being produced by heavy braking; on the other hand, the slot helps in sweeping away gas as well as dust, which comes from braking.

Are drilled and slotted rotors lighter?

Cross-drilled rotors are lighter than slotted rotors which are lighter than plain rotors.

Are drilled and grooved discs handed?

Generally clockwise as it drags the gasses outwards, but it doesn't really matter. Very few of them are actually handed, and it doesn't make the slightest difference in practice which way they are fitted.

What causes grooves on brake discs?

Over time, grooves will naturally develop on the rotor from repeated contact with the brake pads. But these marks take away from the part's capacity to slow the vehicle, as well as cause vibration and pulsation that can be felt in the brake pedal.
