so are drum brakes really better?

The more I hear about mechanics talk about drum breaks the more I think they are better than caliper. Calipers are only good because of high speed fade negation. Drums are better all the way around for every single other thing.

So is it best to have caliper front and drum back? Maybe they should all be drum. Obviously calipers are cheaper to make and easier to service and install but honestly drums are better and I could list the reasons why if you really need help.

        if you can operate a vice grip and slap shoes for 5 minutes you can fix drum brakes.

    If they sucked disc brakes for semi trucks would be infinitely more common than they are now

      Good point. They are better imo. Only for performance cars, no trucks or vans

      That's because drivers don't know how to downshift and constantly smoke their brakes. I wish I had a picture of the pile of drums at work from school by drivers warping and cracking drums from the hills going in and out of town. Like drop it down a gear and slow down at the top of the hill.
      Drums are amazing for raw stopping power longevity and as long as you aren't racing or left foot braking constantly you will not notice any appreciable difference on drums that have been properly assembled and adjusted.
      Drums also mean they don't have to have a separate parking brake system for passenger vehicles so usually if your rear brakes are working so is your parking brake

      Drums handle heat better which is a way higher concern/factor with big rigs. Also discs cost an arm and a leg for them

        Are you talking about heat in terms of Temperature or Dissipation? Cause if it's the latter then it's literally the fricking opposite.

      Its more cost effective to run drums than discs. There's also a ton of lobbying involved with trucking which hinders advancement. In I'm pretty sure in europe most trucks run discs now anyway

    You're not wrong, drums are excellent for everything but heat dissipation and thus, performance.

    However, Drums are notoriously annoying to service, especially a full Hardware replacement.

    >So is it best to have caliper front and drum back?

    Yep, essentially this. Under hard braking your rear brakes contribute only about a quarter to a third of your total braking force, which allows your Disc fronts to bear the brunt of the friction heat.

    Meanwhile, under light braking your rears engage first and with more force, both to spare friction material of your Discs and to somewhat counteract the pitching motion that braking the front wheels incur.

    As a final bonus, Parking Brakes are easier to implement in Drums compared to Discs, to the point that many rear Disc setups you see will actually have a Drum hidden inside the "hat" that functions exclusively as your Parking Brake.

    Really, most Economy Cars have little to gain from having Rear Discs.

    Having said that, I'd still rather have Rear Discs because FRICK WORKING ON DRUMS OH MY FRICKING GOD.

        The ones that do suck are like on the older dana 60 rears where you have to pull the rear axle hub to get the drums off. Who the frick ever thought that was a good idea?

        The newer sterling rears are so much better because you just pull the tire and back the shoes off and can pull the drum right off the wheel studs.

        The first couple times they're tricky (especially if you have a Toyota cause they do it completely backwards from everyone else) but once you get the hang of it they're no big deal. Ask a boomer in your life to help you out, they can do them with their eyes closed.

    drums are fine I guess, they're just annoying to work on. You can throw new brake pads on calipers in like 15-20 mins, drum brakes end up being a project and a half if you aren't working on them every day. Calipers also perform better I think, and its not like modern brake systems are known for failing, they've got the recipe pretty dialed in now. The only shitty part is that rotors are annoying and expensive to replace, and kind of delicate I guess, but you generally don't need to change those anywhere close to as often as your pads or calipers

      would have included this if I saw you commented before posting, but I used to work in a heavy duty shop and did lots of services on vehicles with drum brakes (local farmers would bring their shitbox farm beaters in because we would turn a blind eye to safety requirements and do a lot of "good enough" fixes that you couldnt get away with for vehicles that will be insured/safetied and driven on public roads).

      They're not THAT bad. you just take off the cover, a few bolts and pull out the brake shoe springs to get them loose. Its just the fact that you have to frick around with springs that people dont like, and the drums are sort of famous for being really seized on and hard to get off in a way that doesn't feel destructive if the brakes aren't serviced often enough

      i've mentioned this before but if you want them to last even longer, cryotreat them. guy i took my rotors to get treated had his delivery van's rotors replaced at about 30k miles. the new set he cryo treated and last time i talked to him, he was at a little over 110k miles on them

    The fade resistance is what matters since it’s what’ll frick you up.

    >get back on highway and try to get off at the next exit.
    >no fricking brakes

    It’s the reason we have runaway truck ramps and all sorts of rules for trucks in hilly regions.
    Having brakes that work trumps every other consideration.

    Would ventilation improve it's brake fade issues? Like "drilled" holes, vent ports on the casting, or through backing plate?

    • 2 months ago

      probably better to have vent slots/ports on the backing plate. angle them so that the air flowing past creates a low pressure zone forcing air into the drum and out the slots. kinda like those reverse scoops on hoods.

    In an econobox it really doesn't matter. Yeah they're harder to replace but they last 150k plus miles who cares.

    Is it true that some drum systems are self-adjusting? I vaguely remember reading that some implementations did 'something' to the shoes when the car was driven in reverse for several yards.

    • 2 months ago
      Anonymous

      Ones meant to be used purely for parking brake are not. Everything else is self-adjusting. Old VW's had the simplest mechanism for that. Whenever you brake and the shoes press against the drum, that little wedge on the right gets pulled down by it's spring, making the shoe's resting position closer to the drum

    imagine thinking that complicated contraption of springs and plates is better than just pressing a pad to a disc lmao

      They have far more shoe area and far more pressure that naturally wants to collapse. Calipers have huge downsides.
