“Honey, is he still out there shouting about brakes?”

“Sure is. He’s been going since 2am this time. The police came at 3 but he ignored them, then he stopped for a coffee at 5 but he’s been flat out since then.”

[ImGoingSupersonic]

He started filming at dusk and ended at dawn. What a hero

[billhill]

I had a 61 chevy pickup with drums. It took me a quarter mile to do a panic stop. Pucker factor = 11

[hey_buddy_waz_up]

I remember when GM proudly declared "Disc Brakes" on the brake pedal back in the 70's and 80's

Scotty,   you're a straight talker with integrity. It is great to experience that rare quality in this day and age. Much of your advise and insights is much appreciated and some resonates with what I was taught 40 years ago. Keep up the good work. Your efforts are much appreciated!

[markbeaulieu]

Scotty has a dream about brakes. Wakes up and does a video about brakes at 3am AND you can’t forget the shades cause those lights are too bright!

[ElusiveMasquerade]

Scotty is always down to earth with his explanations. He’s a true mechanic and I love this channel.

Scotty, I remember talking about this 35 years ago in college. The professor said that if you need to stop the rotation fastest drum brakes are what you want. But to have controlled breaking or not or not to instantly stop, disk works best.

[tomlemole]

I love how Scotty speaks to both the how (direct technical explanation) and the why (history, design choices, degree of importance, etc.) for all of these basic auto issues. You can't beat a good "Pros & Cons" video. ;)

[igorblyat]

Why did you film this video at 3 am? Did you like have a nightmare about drum brakes and disc brakes lol

[soilmanted]

Nice explanation. Scotty got it right this time. But he left out one of the reasons for putting drums on the rear – the parking brake. You don't want to rely on hydraulics to keep the car from rolling away after you get out of it. You want a strong, mechanical linkage to keep the friction surface firmly in contact with the drum or with the rotor. With rear drum brakes, a simple cable from the handbrake lever to the brake shoes, and another lever attached to the brake shoes, can keep the brake shoes in contact with the drum. What kind of mechanical connection are you going to use to keep the friction pads in disk brake caliper in contact with the rotor? While some cars do have some kind of mechanical connection to keep brake pads in contact with rotors, the solution for other cars is to use a combination system which has a rotor and small drum cast into a single unit, and small brake shoes inside the drum. So now you have disk brakes AND drum brakes on the rear. Now things are getting more complicated, and heavier – heavier than plain rotors would be, and possibly heavier than plain drums would be – defeating one of the advantages of disk brakes. Might as well just make the drums a little bit bigger, and dispense with the rotors.

You know I've been watching a lot of Scotty's videos in just the last year and I've learned a hell of a lot. I don't agree with everything he says all the time, but I mostly agree with what he says. And he obviously knows more than I do so I've learned a hell of a lot also.

[cybrarian]

Thank you for this incredible education, Scotty! You're like the "uncle" we all need to ask our car questions to.

[mandolinic]

My car is so old, its only brake is an old shoe on the end of a lever rubbing up against the edge of a wheel.

[Kacpa]

My 1990 Celica has all wheel disk brakes. It depended on the trim. Lowest trim level Celicas had drums. Everything else in the lineup had all wheel disks.

I just can imagine scotty's neighbours wearing wireless headphones when watching tv.

[joshualaw]

I was actually thinking about going from disc brakes to drum brakes...


*...on my bicycle.*

[chrishunt]

Slotted rotors have another benefit. I use slotted rotors because I live in an area with TONS of dusty dirt roads. I found that normal discs if you don't get rain after a while get dust packed between the rotors and pads travelling at higher speeds down dirt roads. Which I've had cause a lot of brake loss. Slots give a place for the dust to go and get blown out.

2017 Tacoma owner manual says that the rear drum brakes can ice up in winter if you use the parking brake at night. Water ice can form inside the drums and you'll be stuck until you can thaw them. Sure enough, some owners report their trucks are locked up in the morning after a freezing night.
