I am not a mechanic. I believe I can do a brake job on the rear axle of my Caprice in 30 minutes if I hustled. I generally don’t like to rush and I like to relax and marvel at everything, I do think if I really pushed it I could do that though.
Full disclosure, my drum brakes are generally pretty clean. When I rotate the tires I tend to take off the drums and dump out the dust that was sequestered by the drum so my brakes are generally pretty clean and I dont allow my backing plates to get in bad shape since I always lube the shoe contact points when I do a brake job.
If I did a quick and dirty shoe slap I am sure I can do it in 15 a side. I do have all the proper tools.
Yeah, I’ll get right on that as soon as I find a car around here with drum brakes.
Yes. I believe that at that time NAPA was using the same remanufacturer as many other suppliers, and that may explain the recurring failure. I was using Centric at the time and their top-tier line was good and I don’t recall any repeat failures of that RF inboard lower piston sticking.
2, 4 or 6 piston calipers are madness. Trying to clamp down on the pad with so much force when a measly wheel cylinder can start the self actuation in motion on drums snd habe constant force a caliper only dreams of.
Drum brakes are like a finger trap, the harder you pull the harder it applies.
I’ve had many complaints of “grabbing brakes”. Braking performance of drum brakes can be inconsistent if the equipment is compromised. Broken springs, too little or too much shoe/drum clearance, contamination; many problems with drum brakes.
Have y’all seen the new high performance drum brakes from the top brake engineers, like Brembo Brakes, for the Sports cars, Supercars and even the 220+mph Hypercars yet???

Drum brake’s self energizing ““feature” is exactly why they can no longer be used on the front of European cars.
Why? The self energizing feature makes the left and right brake forces to be too different that they do not meet the German TUV nor the Brit MOT test specs. This is especially critical on front brakes because they do 70% of braking.
My 10yo Trek has disc brakes. They are far superior to the old stye brakes. Took some getting used to because of how much faster they stopped you. I think they’re standard on the E-Bikes (I don’t have an E-bike).
It is amazing that the more you talk, the more you show you don’t understand automobile and light truck brakes…
My 1993 Chevy Silverado C1500 Extended Cab short bed RWD truck with a 5.7 has 11.6" rotors w/single piston front caliper brakes and rear 10" drum brakes, shoes are 10"x2.25" and weights in at 4,100 lbs…
My 2023 Toyota Tacoma double cab short bed RWD truck with a 3.5 has 12.5" rotors w/4 piston front calipers and rear 10" drum brakes, shoes are 10"x1.98" and weights in at 4,200 lbs…
So the 93 Chevy has wider rear shoes making more contact with the drum, and by all things giving per you, should have a greater stopping force… but…
The trucks are very similar in weight and brakes size, other that one had a single piston and the other has 4 piston calipers, ABS has not activated (no feed back) to be the difference… That being said the Chevy stops normal, nothing to wright home about, but ■■■■ that Tacoma with the 3 EXTRA pistons will about through you through the windshield, it will stop on a dime and give you 9 1/2 cents change back…
So @Old-Days-Rick, why will the Tacoma with more pistons but smaller drum brakes out stop the Chevy with less pistons but bigger drum brakes???
Hmm, I don’t know how many pistons in the caliper but my 13 Y.O. F150 has discs on all four corners. I don’t know if the ABS ever activated but always stops in a straight line.
We have to keep this thread going at least until May for it’s six year birthday party.
Almost exclusively at this point. Similar to Mike, every bike we have has disc brakes for the last 12 years. Also, all the electric motorcycles (we have 4), atv, scooters and my son’s e-bike are all disc. The e-bike had some lousy OEM brakes though. I quickly bought some aftermarket cable operated, hydraulic calipers and new pads and it will practically throw you off it now if you brake too hard.
Yeah, you can tell it’s been a while since I bought a bike. Pretty much the only ones now without disc brakes are some of the cheaper Walmart bikes (even a $150 one has them) and ‘cruiser’ type bikes.
