Brake issue.Tire skipping and chirping at DE

Recommended Posts

Hi All,

This will sound strange. I have driven in over 25 DE days and run solo in the white run group. When I brake hard on the track my front left wheel chirps and i get a little movement in the steering wheel. The front of the car sceems to dive a little from side to side. I feel like the car has more braking ability but it cant reach it because of the chirping and loss of grip

I have changed the following with no apparent difference to to the issue

1. I have changed the brake fluid and the brakes lines.

2. I have change to new rotors changed pads from stock to Hawk hp+

3. Changed tires from bridgestone to Hankook Rs2(great tire)

4. no visable difference in the pads and tires wear form the front left to front right.

5. inspected my brake calipers all look good


I changed my suspension to the eur M030 I suspect the issue was not there before the suspension change but i am not sure as I was not driving as fast then.

I have noticed that my brake pads ( front and rear) all wear at the same rate no matter which compound I use. I hear from othere at the track that they replace their fronts twice as often as their rear pads.

I also notice that the chirping is more noticeable when I am on my own in the car but when I have a passanger it is less.

It has been suggested to me that i may have bad ABS/ bad master cylinder ,car needs to be balanced.(how do you balance a stock suspension)

I am planning to change to r compound tires and run Hawk DC60 fo the next event in August. but i dont know how they will effect the problems

My car is 1999 c2 manual cab with no PSM and no traction control.

I do as much work my self on my car as possible.

Thanks in advance
