vibration on the brake pedal

I bought 4 new tires for my vehicle, there was tremor in the steering wheel, the rod was cut after the start, but the brake pedal started to vibrate (not doing it at low speeds above 90 100) I think my guess might be from the disc, waiting for your answers ... & nbsp;

As you might have guessed, it's probably from discs.

You can make new tires too, sometimes the tire needs to get used to the car, maybe you can do it too. & nbsp;

what could be the cause of hardening of the brake sometimes in my vehicle

After the brake is applied to the brake, the pad and discs harden (swell) due to the increase in temperature, it is normal. I think that the hardening other than this may be caused by the pad.

Never use water with discs that become hot during long-term braking use.
