Rear Drum Vs Disc

Who's ready for a stupid question today?


I've currently got Front Disc and rear Drum; why rear Drum and not all 4 disc?

what is the advantage to having rear drum?

it is work converting the rear to Disc?

 

Short answer:
Not worth it.
From what I've read, the brake system on our trucks don't push enough fluid to the rear brakes so when you install calipers and rotors they don't work as well as the drums we have currently.

Why Toyota didn't do disc all the way around... no clue.

PS: If you want to read up on the subject https://www.google.com/webhp?source...r+disc+brakes+tacoma+site:www.tacomaworld.com

 

I don't think it's worth converting to discs for a small optimal change in performance and aesthetics.

 

interesting... thanks for the link

 

from the link @eccracer104 posted, it looking like paint them black and call it a day...

they're not work messing with .

 

the Colorado has rear disks and it has a 60-0 of 131 ft
While the tacoma has 60-0 of 125ft on the offroad and 132ft on the rest of the trucks

 

Why mess with what works. The trucks will sell themselves no matter what Toyota does lol. I like the look of discs personally.

 

I like the looks of discs too, a nice smoothly sanded down drum with fresh paint looks ALMOST just as good.

 

I'm just lazy and don't like working on drums

 

IF discs were better, then why do cargo semi-trucks/ trailers use drums?
If the Chevy Colorado uses discs in back, that is just another GREAT reason for Toyota not to!!! LOL

 

Drums but with air and some actually do have hydraulic disc brakes

 

Rear drums on these trucks work fine, but as much as a new Tacoma costs, there is no excuse in my opinion for them to come with drums. To answer the OP's question, no, it's not worth it to convert to rear disc brakes. JMO.

 

I want rear discs for 2 reasons.

1. They look awesome.
2. I hate working on drums.

 

I had an S10 (same thing, but older name) with 4 disk brakes. Don't know how many times I had to redo the back brakes because they ROTTED and ROTTED and ROTTED. Something about having all that salt crap spraying all over it every winter and not nearly enough work from them to keep them clean.

 

On the contrary, it takes a higher psi to compress drums over disks, going to disks, to do it properly, you would need a proportioning valve that will re distribute the brake fluid psi properly to each wheel, or your rear end will lock up real easy on a hard brake (with disk in place of drums). Drums have an advantage over disks for vehicles that have a heavy load, you get the forward momentum that helps engage them.

You can get a rear end setup that will function just as good as the drums, but I do not believe our trucks have the ability to change the proportioning valve, in the TRD OR I believe it is build into the master cylinder. There is a conversion out there that basically pulls the rear end off a Tundra, but not sure how they re proportioned the fluid pressure. But the tundra is also in a completely different weight class than the tacomas. I met a guy who did it and he cannot get the brakes to function properly, but his truck was purely a desert prerunner, not street driven.

 

Thank you for the correction! I knew there was something to do with not having the correct pressure, but it has been a while since I read on the subject. Thank you for providing the correct information

 

There is a 4Runner conversion. I am still amassing the parts. Sold by www.tundraracing.com. Just have one caliper left to purchase. There are also adjustable proportioning valves availableto purchase, if there is a problem.

Another point: People who off-road through silty waters, muddy waters, can have their drums' shoes wear out incredibly quickly. Happened to me, and other members.

The foreign sediments stay in the drums and continually wear out the pad material, much faster than without. Disk, it is much harder for that sediment to stay.

So disk brakes are the sexy 20 year old you keep for the weekend and Drums are the reliable wife you keep for the long haul.

Got it.

 

I'd still rather have discs. How come 4Runners, Tundras, Wranglers, Range Rovers and just about every other truck on the road now have rear disc brakes? For 40k and up I WANT REAR DISC BRAKES!!! Sorry about the rant. I'm cranky today.
