Above is inside your brakes. Technically, fluid is what stops you when you depress the pedal.

1 – the calliper, which contains the pistons
2 – the brake pad within the calliper
3 – which clench the rotor

How it works: the brake fluid pushes the pistons within the calliper > which in turn pushes the pads onto the rotor like a vise > and slows down the vehicle. The harder you push on the pedal, the harder the pads push on the rotor.

It’s a good idea to check the condition of both the rotors and pads, as well as the colour and level of the fluid.

Above are the old & new rotors.

My neighbour taught me while changing his.

The pitting on both the pads and rotor is what caused the car to stutter down the road during our test drive.
