Rear disc brake swap

from what i have been told so it could be major bs but toyota put the drums in for two reasons 1)during off road use there will be less crap getting in there vs disc 2)they designed the truck knowing that it could tow but it has a low rating and was not its intended use so drums were just fine

perfectly said, i tow and the brakes suck as well as added weight from tires etc. just slapping in disc does nothing even possibly degrade braking performance UNLESS you add a better master plus when its time to redo the brakes they will be easier although it will have to happen more often just get lifetime pads and rotors like how i did the front so you never have to pay again

 

it depends, are we talking just a 60-0 or lots of 60-0. just your basic panic stop, if your current brakes will lock them up and trigger abs then these larger ones wont help as your limits are your tires. I know with 33s i have no issues locking them up with the factory.
now towing down a huge hill, they will make a difference.

 

I feel alot of those who complain about braking on the tacoma have a Non TRD OR 4x4 09+ ... aka a tacoma with a standard vacuum assist master cylinder and separate abs unit. Those (like my truck) that have the electric boosted master cylinder have 2x the line pressure at the same pedal pressure as the vacuum assisted trucks..... I can lock up all 4 tires on dry pavement REAL quick with abs turned off if im not careful.

And towing etc... use your gears. A rear disk swap will not help out brake fade in this case.

 

Just because ABS kicks in does not mean your are getting any better braking, my ABS is f-ing scary and my braking distances are absurd because my OE system is trying to stop a pig that is severely overweight. Alpha tests have already been conducted using the master cylinder conversion with great results and betas are in progress, I'll have results to share soon.

 

Your truck is essentially stock weight which is why you feel the brakes are fine, put 1500 lbs in your truck ( loaded expo build ) and daily drive it and tell me how wonderful those brakes are...

 

I don't believe it when 90% of the vehicles in 2017 have rear disks

 

Just because the brakes are from a heavier vehicle doesn't mean your 60-0 is improved with those brakes. It doesn't matter how heavy your vehicle is, if your existing brakes are strong enough to lock up your tires then you're gaining nothing (at this point the difference comes down to traction) except maybe cooling, and I'm not seeing rear brakes overheating before fronts.

For those concerned with performance from the stock brakes when towing, you're doing it wrong.

Heavy trailers have brakes. Install a brake controller and use it.

 

Heard a rumor about swapping front and rear brakes with Tundra brakes... anyone have any info on that?

 

if anyone has driven a newer 4runner but when i drove them at my old job renting cars those things would stop on a dime like almost sent a few of us through the windshield (not really but we were on the dash) and those have disc on all four so im not really sure why they didnt on the taco I mean mine stops good enough but definitely far short of the 4runner

i agree as well thats why idk what to believe

 

that combined with downshifting will help but sometimes feels like it falls short and when in a pinch using a trailer thats not yours then it may not have trailer brakes making the controller essentially useless

from what i believe it has been done but again it needs to be accompanied with an upgraded booster

 

newer 4 runners likely have 1. like mentioned an electric boosted master cylinder. 2. they have larger diameter FRONT disk brakes.... the rears hardly do anything.


The "tundra" upgrade was done on 1st gen tacoma's and 3rd gen 4 runners.

You can upgrade to the larger diameter 4th/5th gen 4 runner front disks / calipers on a tacoma but you must use a 17in rim.

 

good info still trying to learn everything hence all the i believe etc statements

 

That is exactly it the current brakes are NOT strong enough to handle an extra 1500 lbs on a daily 100% basis. I don't know how else to explain this so let me be very direct - my brakes suck, they are fkn scary, they don't come close to locking up. The problem is not traction, the problem is that it takes an extra 100ft to stop. My truck like many loaded expo rigs is 1500 lbs + over stock and the OE system was never designed to handle that weight and stop you within a reasonable distance.

 

Sorry but you got quite a bit of this wrong :


1. The Tundra upgrade method can be done on a second gen, there is a whole DIY thread about it. Quite a few people have done it and it is only $500 all in using over the counter remans.

2. In regards to the " rears hardly do anything " - not true. The T4R has far more weight over the rear axle than a Tacoma and I can tell you that from personal experience as we also own a T4R those rear discs do a lot. As someone else stated the T4R brakes like a sports car and it is not just because of a You also can't compare a stock trucks performance or form an accurate opinion unless you are driving a truck 1500 lbs over OE weight with 35's etc in a daily basis.

A T4R rear caliper moves more fluid and connects with more power without fade than a Taco drum.

3. The T4R does not have a larger front rotor, use any auto parts store web site and look up for example my pair 2006 4WD Taco and a 2007 4WD T4R...pick others year and you will see the same :

A 4WD Taco uses a 319mm front rotor

A 4WD T4R uses a 319mm front rotor

 

@Evenflow, you have a build thread?

Towing a heavy trailer without functioning trailer brakes is going to be sketchy, even with a big brake kit/rear disc brake conversion. Physics is a bitch when you have 5,000 lbs trying to pass you when stopping.

Also, not sure if you have towed with an off-road, they have an upgraded brake booster.

 

Edit - finally made a build thread link is below.

No build thread, never been motivated enough to do it and I can't handle rejection...just the same shit everyone else has ( sliders and full skids we're off in these photos ...that's another 300 lbs )

 

SUPER clean. Love the bed setup.
