I am now out of ideas trying to solve a very heavy metallic "knock" when I press the brakes hard and quick.
If the car is rolling (slow or quick) there is the loud "knock" if i press hard and quick, if it's stationary there is no noise at all.
The car drives very well and brakes ok...
Is it "okay enough" to use two head gaskets to raise head and relieve too much compression on probably twice shaved head already installed?
Appreciate any comments about potential of this simple maybe easy fix.
Please don't be shy.
