I think GP mistook a short summary for FWD that it “drives” on front wheels, as in it delivers engine output to front wheels.
fyi to all, brake hydraulic lines are still distributed to all four wheels in low-end cars, but “drum” brakes are often used in the rear, which stretch out to slow inner wall of a cylinder rather than squeezing together to hug on surfaces of a disc.
- brookst 3y agoAre there any modern (post-1990) cars with drum brakes? Discs are simpler and cheaper and work better and are much easier to service.
- numpad0 3y agoDiscs are also exposed to wind and sand, drums aren't. Front discs and rear drums is just fine for commuter cars, ID.4/Q4 E-tron uses that if an example is needed.
- brookst 3y agoThanks for the example. They’re not regenerative brakes, just rear drums?
- numpad0 3y agoI don't see the point of continuing this comment tree.
- geor9e 3y agoOther guy lost interest, but a wheel being able to regen brake just means theres an ungeared electric motor on it. It's basically free for the manufacturer to add the feature, so they all do it. Mechanical brakes are seperate and still required for harder braking.
- geor9e 3y agoMy 2009 has rear drum brakes, actuated by the handbrake. The front are disc. It sound like folks are adamant that the brake pedal actuates all 4 of my brakes. I didn't know that. Sounds plausible, I never really thought too much about it. I'll take their word for it.
- geor9e 3y agoThank you - you're right I did assume that. Plus the fact that my handbrake only actuates my rear drum brakes (and sends me into a fishtail drift). I didn't realize my foot pedal was also actuating that, but if so sounds like a smart design.
