The Underappreciated Drum Brake

When I ran the text from your post through an AI detection tool, it explained multiple reasons why your post was either AI-generated or generated by a “content farm” tool.

If you’re going to use AI, then at be clear where you’re getting your data from. (And proof read it to make sure it’s correct before you put your name on it.)

AI = Artificial Idiocy!

I’ve been saying such for over a year now!

“Anti-Intelligence” is another take on it.

Not kissing any tuchas here, but I think Rick is for real.

Just because he and I think differently than the majority of contributors here, or have different opinions, that does not mean we are “AI”.

Really? Want to race? On drum brakes you have a minimum of 3 springs to deal with, plus the clips that hold the shoes in place, plus the parking brake attachment, plus you have to work down the brake adjuster, plus you have to align the shoes before putting the drum back on. And then when that’s all done you have to open the access port to adjust the shoes. Bleeding calipers is a 1–2-minute job per caliper.

To replace just the pads on disc brake you remove one bolt and then tilt the caliper up and out of the way. Remove the pads and then replace the hardware kits and put on new pads. Then you remove the bolts for the slide pins. Clean pins and regrease and put back in place. If you’re familiar with that particular setup you should be able to do each brake corner in 15 minutes or less. I get real quick on my 05 4runner because they had a design problem with their front calipers. I was replacing them every 16 months or sooner.

I agree, I used to be able to properly replace rear shoes and hardware faster than another pro mechanic could properly replace front pads on a 1st gen Chevrolet Cavalier, I raced and won more than once, I was VERY fast doing most rear drum brakes back in the day…

Now when you are dealing with rear screw in calipers (e-brake calipers), that adds a lot of time and slows you down even more… I always found rear drum brakes easy to replace on most cars and light trucks, however some of those rear drum brakes can be a night mare when you have big hands I will admit…

And NO Rick, that doesn’t make drums better…

My point was that Rick said his post was “From a top expert…..”. It wasn’t.

He never showed the wording he used in his AI query.

He easily could have asked it “Tell me the ways drum brakes are better than disc brakes on cars.”

And given that LLMs do ingest bad data, it likely obliged.

Lost me at “LLM”.

@ChrisTheTireWhisperer

I just googled LLM

Large Language Model

YOU :index_pointing_at_the_viewer:t4:could have also easily done that

Hmm, Large Language? Words with more than two syllables?

The information I got was from a trailer expert website as I had stated. Maybe you are not using your tool correctly. Maybe they used AI.

I Hate AI. Its becoming a real problem and people who disagree with facts blame AI and that’s an easy cop out as far as I’m concerned.

Maybe they used AI, maybe not. I have no way if knowing this. Regardless this information is correct I believe. The company I quoted is based in New Zealand and has been on business for almost 30 years.

I am going to email them and inquire about all this before I rain on their name. This is a legitimate, expert company.

I gave that link to Gemini, Claude, and ChatGPT, and asked if the content was generated by AI.

Gemini and Claude were confident it was AI generated.
ChatGPT thought it was but left room for it to be manually created.

I believe it is because we have exceptionally analytical minds and we are truth sayers. I tend to rub alot of people the wrong way even in face to face interactions.

I quoted a reputable company that are top experts in trailer brakes and drum brakes.

People didn’t like what the top expert stated and tried to discredit it all with accusations of AI usage. I don’t know if this company used AI or not. They stayed matters of fact regardless.

When I state matters of fact to my wife she sometimes gets angry. She then gets even angrier when I tell her that I am simply stating matters of fact.

Just in this case, I told everyone this was information from a top expert, a company with 30 years in the business and likely even longer in the field. Accusations of me using AI quickly were thrown around due to checking it on a “tool” which is also likely AI.

Maybe the company used AI I dont know. I doubt it.

I definitely am real, I have been here since 2013 albeit under different names. I dont think AI was as prevalentor sophisticated back then, it certainly wasn’t as accessible.

I lost my original account, WheresRick information when I broke my laptop. I couldn’t get in my email either, I lost alot of information and credentials when I broke that machine.

Ok, I don’t doubt it. Is the information still relevant though? I mean they talk good and bad about both kinds of brakes. Both have advantages.

I just cant see using only 30 percent of the available friction area when a drum uses 80 percent. Drums also require less energy to actuate.

Well, I’m SHOCKED! (sarcasm, if you can’t tell)

Rick, you confuse your strongly-help opinions as “truth” and “facts”. You’re now wandering around trailer web sites trying to support your wrong-headed claims. We are only interested in what braking system works best for passenger vehicles. The clear winner is disc brakes, they save lives by preventing collisions. Are drums cheaper? Maybe, but I value my life much more than the slight additional cost. Even the truck site states that discs brake stop better than drums (“Air disc brakes offer 17–33% shorter stopping distances”), and that the drum advantage is cost.

Is your “Top Expert” an engineer or a salesman?

Sure. Nevada, davesmopar, and I all agree that drum brakes don’t really take any longer to service than disc brakes. I don’t know how many brake jobs you have done in your life, but I’d guess that the three of us have exponentially more brake experience than you do. Sure, you can hand-pick a really easy example or a really difficult one, but over the long run on various makes and models, brake pad vs brake shoe replacement will be nearly identical times.

And I can do brake shoes in 15 minutes or less as well.

I love Toyotas but yeah, those 4-piston calipers on the 4-Runners were a reliable source of brake work. Did you never replace the calipers? Supposedly the aftermarket had a reman caliper that corrected the excessive wear on the RF inboard pad.

The company was started by an engineer.
