The Underappreciated Drum Brake

My ‘04 Avalanche has 2 caliper pistons on each corner.

My Mustang has 6 pistons in each front and one one each rear.

The nice thing about the cable operated, hydraulic calipers is they can directly retrofit onto a bike that had stock mechanical disc brakes.

There were discussion groups around my particular e-bike grousing about the brakes and one guy posted the details on his swap. Once I knew what directly substituted, I could look around for those and other direct fit options.

It took longer to make sure I had the front and back ones correct and in the right orientation than to mount them. The cable interface is the same, in the same position and the mounting was identical.

These are similar to the ones I bought for $50. Hybrid design, self contained hydraulic brake caliper, cable operated:

The improvement was nothing less than spectacular. It was downright scary with the OEM brakes and after the swap, a totally different experience. Good luck with your project!

@Old-Days-Rick I think your Caprice deserves rotors and Wilwood 6-piston fixed calipers front and rear

Hi Triedaq,

Good to see you. You probably also know what strange “instuments” Les Baxter used in his orchestra in the early 1950’s. :wink:

It stops so good now I can’t complain. I believe i am going to take it off the road. I am questioning if it is responsible to keep driving a gross polluter.

I really shouldn’t be driving a V8 anything. But no one else worries about it so why should I.

Not sure yet.

I worry about air pollution. That’s one of the reasons I drive an EV.

Why? My truck has a V8, I would like a V8 car, Cadillac Blackwing! I have a Turbo-four in my car, great, but would still like to have the V8. Only exception would be Miata.

On to 500 posts! Doing my part!

Onward to 500. Another comment on my V8 post. In my 72 CJ5 the I-6 may have been a better choice than the V8. 6 had a 4 speed, V8 only had a 3 speed.

I’m a/the Black Sheep of the Car Talk family, I have a gas burning V8 that gets single digit MPG most of the time, and I plan on making it worse… And I love it…

But sadly my 2023 Tacoma gas mileage sucks, but that has a lot to do with my short trips, and YES it burns the heck out of gas at idle (mainly drive throughs)… My best short trip (5-10 miles) MPG is 19, but my average over the last 6 fill ups is 13.8 MPG


Gas prices are using Kroger fuel points at Shell…

Just had to say something so help get to that 500th post…

Welcome to the club!

The problem was when the majority of vehicles got single digit MPG. Back then, you had to love the smell of partially burned hydrocarbons in the morning :rofl: Now I get nostalgic when an old car goes by and you can actually smell the fumes, especially one burning race gas…

Would I like to return to the old days? Of course not. The thing is, you never used to notice it because they all did it. Now it’s like someone sparking up a cigarette, you can smell it a mile away…

When I was a kid, I never realized how much blow-by I was smelling when we sat at a traffic light. Then–slowly–after PCV systems were introduced in the early '60s, and the amount of blow-by began to decrease, I realized just how much of a crankcase stench used to permeate the air.

Wowser, the Coyote in my F150 4x4 gets never gets less than 16 MPG.
When George was on the site I suggested, and still would if mine and had the $$$$, get rid of the 302 in his truck and get the biggest, baddest FE I could find.

I just don’t know if I can give this up. One if the top cars ever made.

Plenty of people roar around here spewing black smoke from their illegally modified diesel pickup trucks, so why should I be the one to try to save the world.

Back to the title of this threat. As some of you know, I was in high school in the sixties. Dances always had a live rock band. Ever band had a drum brake*,drummer got a 3-5 minute solo! Every drummer was the next Ringo Starr or Charlie Watts.

  • yes, I know, break not brake.

That “masterpiece” is one of the models listed in this book:
:smirking_face:

It is featured on pages 20 & 21, in the chapter titled, Badly Built.

I spent a couple of years driving those Caprices while the Killer Whale version was in development. We were working on electronic shocks for that boat.

The frame was so flexi that on ripple bumps the shocks did not move… but the frame and body did! The ox-cart solid axle would pound and skip sideways over rough roads. The flex made it ride like jiggly jello. You hit a bump and it took a couple seconds to quit shaking. Same when you slammed the door. They wallowed like a boat taking a corner in heavy seas. We used to have to tighten every bolt in the front body structure because they were not tight from the factory and the car rode better once you did tighten them. At least cops ignored them when you were speeding - they were driving them, too.

Even GM’s subsidiary, Opel, had a model with more structure better handling and better ride; the Senator. It was unibody car with independent rear suspension. Hit a bump and it was over. Turn a corner and it would lean but not wallow. Spent a lot of time in those, too.

That looks exactly like the one in my neighborhood, with the exception of the color . . . The one in my neighborhood is :poop: brown :sweat_smile::rofl::joy::laughing:

And you clearly can NOT let it go😜

500!!! And to keep it car-related, those Caprices were the ‘hot thing’ when they came out, many popping up in River Oaks, one of the expensive Houston neighborhoods,

I always liked Opels. The Senator model wasn’t sold in The US, but the Opels that were sold here seemed like decent cars. In fact, my foreign car specialist, to whom I took my disastrous Volvo every few weeks, suggested that I trade it in for an Opel.
