Rotar to disc conversion?!?

I have been looking for a rotar to disk conversion kit for the truck.. Anyone have any ideas?

 

Do you mean a Drum to Disc conversion?

 

Wrong area brother.. Move it to 2nd gen... And I had ask the same question awhile ago. Wifes 4Runner has disc on rear why not Tacoma? Issues with clearance and booster.. Not worth the money for the pay off..

I'VE THOUGHT OF DOING THIS SOMEDAY, BUT NOT AT THAT PRICE.

 

word thanks for the info.

 

Moved over to the 2nd Gen Forum...and mjp2 is probably the best person to comment about this....

 

don't do it
i had a friend that did it on his and nothing but problems

 

Ugh,

I wish there weren't comments like that (well, more correctly, I wish there was a kit that worked, didn't have issues, and didn't cost your first born).

I want to do the same conversion, and definitely -35 points on Toyota's end for not having this standard (or even an option????)

Nonetheless, thanks for those who chimed in with real experience and saved many of us some coin and trouble.

Discs would be awesome (and are far superior to drums, IMO).

 

Sounds like you have done some good research on this. Too bad, even the GM's offer rear discs. I was really surprised that Toyota doesn't address this. As a consumer, I promised myself my next ride would have rear discs... then I bought the Tacoma... couldn't resist.

Discs are cheaper to maintain across the board and have fewer failure points. Maybe Toyota can listen and implement this change in future builds.

 

Drums on older cars never failed. They are proven, don't worry about it. For all-around cars, not racing cars, rear drums are effective and more than enough.

I once had a Jeep Patriot with disk on 4 wheels and the braking power isn't higher than the Tacoma. In fact, my Tacoma with rear drums has a best braking power of all car I owned. It brakes so well that I don't need more. It all depends of the design and parts. So, I agree with mjp2.

Anyway, it's on the front that the brake pressure is higher. Something like 70% front, 30% rear.

I don't understand the desire to put rear discs, except maybe for cosmetic purposes. I don't think you speed at 200 miles per hour and you don't use brakes more often than driving (heat buildup) ...

If you need more braking power, well, go see your dealer, because something's wrong with your truck

 

What does it do to ABS?

Does it do anything to proportioning valve to increase fluid pressure to the rear? That's why performance is so bad.... might as well just cap off the brake lines and not worry about replacing pads. At least they'll look cool.

And don't carry anything heavy where you'd need rear brakes.

 

I think that's backward about pressure...discs need more hydraulic pressure.

Drums are self-servoing in that the rotation of the drum acts on the trailing shoe to make it bind tighter, with less hydraulic force. Some designs are dual-servoing with a link that transmits the force to the leading shoe and it binds tighter too...really common on trucks. I'm not sure if this one is.

But it makes sense disks get along with less volume because the piston isn't pulled back into the caliper after each actuation and work their way outwards as the pads wear. Wheel cylinders, conversely, have two pistons and travel the total distance each time as they are pulled fully back into the cylinders by springs after each actuation. The adjusters working on a fulcrum make up the travel distance of the shoes as they wear.

 

very informative thread, I have been wanting to put disk on the back of my truck mainly for looks and also to improve braking since I have bigger wheels. I wanted to put drilled or slotted rotors with better pads to increase the performance.

So it looks like the only option would be to retro fit an FJ master cylinder and maybe take other parts off of an FJ to make it work?

 

I did this on my 90' 4runner. there is welding involved, and you need a Wilwood proportioning valve, other than that it was a fairly simple install. I never had any problems. Check out Pirate4x4.com for more info on switching drums to disc on a Toy 8" rear. BTW I used the stock booster as well. The price for that Rear conversion kit is not bad at all. The kit I had to piece together using a write-up a mod gave me from Pirate4x4, and on my 90' 4runner i spent at least $630.
