How The Brake System Works

BlueTuner · 12-24-2009, 05:22 PM

Im new to cars and wonder how brakes work. I have a 89 turbo manual. My questions are When I press on the brakes do all the brake pads stop the rotors or only the front ones, or vice versa the rear rotors are stopped. Also for the e-brake, do they use the same brake pads as the pedal brakes use or do they use a different set of pads and also how does the e-brake work.

On certain cars, there are different type of brake setups

1) Brake Pads which would consist of rotors calipers etc and are normally located in the front wheels.
2) Brake drums, and brake shoes which are common for certain vehicles and are normally in the rear

When you apply the brakes, the brakes are applied to all four, with hydraulic pressure.

For ebrake, they are in the rear, eithr they use the brake pads if they come equip, or on some vehicles they use a smaller brake shoe in back of the brake rotors. And if it is a drum, they just use the brake shoe for it.

The MKIII Supra also has a proportioning valve & Link .Never had one apart on the Supra, so I'm not sure how they work. At a guess, I would assume they distribute more pressure to the front than the rear. All the UK Supras also have ABS, disk brakes all-round and brake shoes/drum for the hand brake. (E brake)

The e-brake/parking brake drum assembly on the Supra is on the rear, and uses the surface area inside the mounting section of the rear rotors as the brake drum. It's a wholly mechanical system as opposed to the hydraulic system used on the regular brakes. The pads for the parking brake are very thin in comparison with the regular pads, and aren't available aftermarket.
