Big Ole' Brake Upgrade Thread for Third Gens

It looks like it's hitting the section below it. These are Stoptech lines via SOS, but they are definitely concerning. I have Stoptech BBK front and rear along with lines. I make sure to get them a bit longer than normal to account for any pull.

 

The rub on the ring below is definitely what caused the failure IMO. I just don't know if the same would have happened with OEM lines? Probably?

I started with the extended lines for my first set. RSG here in town rerouted them when doing a front suspension upgrade. Then they caught on something while turning and snapped off. When RSG replaced them, they ordered the standard length lines per their recommendation. RSG also added the ring to hold the lines in place so they don't snag. Suffice to say I don't take my truck to RSG anymore.

 

ok that makes sense yah RSG prob not the way to go. That's a good call. Yah def how they are routed is key. I had a line loosen as it was rubbing the shock. Since then SOS send me some shaved down ones for the brake lines.

Are you running stock length or Long Travel setups?

When I get home, I can snap a photo of how we ran my lines, but I believe it ran up the spindle rather than out like that. It looks like it stretched it against that deal they added, as you said.

If you are concerned they are still not good you can look into some Goodridge lines which are pretty standard for good lines.

 

Originally, the longer lines because the truck is lifted. But when RSG broke those while in their possession, they recommended the shorter ones saying they don't need the extra length. Then this shit happens because they're too short, and they routed them funny. So Tom at SOS was a good sport and sent me a new set of the longer ones today for free.

 

Wow that is garbage

 

Been running Powerbrakes up front and SOS performance disc brakes in rear on 39’s. Brakes like OEM but a tad hair better.

 

How did you get the rear line pressure high enough to work well with the SOS rear disc brakes?

 

I don’t think it’s the rear disc that’s making the difference for me since I didn’t upgrade the master cylinder. Most of the power is coming up front from the big brake kit. Only reason why I went with disc brakes is so I don’t grenade drum brakes like I did in the rubicon trail.

 

I should have stopped with just the fronts, IMO. They did provide a better braking experience. But the rears only made the pedal feel worse. They don't get enough line pressure to really do much. I wonder if that was part of my front brake line exploding or if it was just the rubbing? Lastly, you can upgrade you master cylinder to the Sequoia '04 to '07 master cylinder to get proper pressure for the rears. But your Tacoma can't be an Offroad or have the electronic boosted brake system otherwise. Wondering if the 2024 Taco w/ 4 disc brakes, if that master cylinder would work? Spindle size would need to be the same (likely) but it would also need compatible wiring for the electronic boost - which is not likely to be compatible?

 

yeah unfortunately I have the TRD pro model and can’t upgrade the MC. The braking difference was really felt once I got the Powerbrakes.

 

Do you think these will do just fine for 35s?

 

So, reading through this and other tacoma brake upgrade threads, I have decided to do the 2010-2014 14WA caliper and rotor upgrade. I'll pick up a set of 17" wheels for clearance, like a set of toyota oem 17x7's off of a 4runner, they pop up fairly regularly locally.

I was originally interested in staying with the tacoma rotor/caliper, however more recent discussion about changes at stop-tech has me deciding that the 4runner BBK swap is the way to go. A 17" wheel for tire variety in the 33" and maybe eventually 35" range seems to be the way to go.

My vehicle is a '22 TRD OR, so it has the electronic boost master cylinder, and I will not be able to upgrade/change this portion of the braking system. But from reading this really becomes necessary only when putting rear discs on. As I do not plan to do this, I will be fine with the tacoma's original booster.

So, 2014 4runner 14WA calipers. In pricing these out, there's a small difference in cost between OEM and aftermarket, so I will go OEM.

14WA caliper P/N's: 47730-60300 Right/Passenger, 47750-60300 Left/Driver.

From reading, the 14WA calipers have the same 12mm caliper bolt as the 2nd/3rd gen tacoma caliper. I do not want to have to sleeve the later 14wb caliper bolt holes, even though it's a simple task- it's two less parts per side to risk losing when doing maintenance.

Rotors-

Originally was considering a stoptech slotted cryo rotor (126.44175CSL and CSR, respectively), but again, I have some questions about changes at stoptech over the past several years. At ~$186/ea these are the most expensive rotor option I am considering.

EBC offers a slotted "High Carbon" rotor for the 4runner, p/n BSD7578 sold as a pair. I am curious if anyone has any experience with these specific rotors, or can point me to any discussion on them elsewhere. Msrp is ~$300 for a pair. So, in between stoptech and oem pricewise.

EBC also offers a black zinc coated, slotted rotor, p/n

$243 USR7578 USR Sport Brake Rotor

USR7578 at about $250/set. I'm assuming these would be a little more corrosion resistant than a non-coated rotor. I am not sure if the "high carbon" rotor is a better option for lifespan and warping considerations.

I do not see any mentions of the weight of either EBC rotor, so I can't relate them as potentially better/worse than the 4runner oem rotor in terms of thermal mass.

OEM 4runner rotors (same p/n for both sides) 43512-60191 are no doubt a good option. I've been looking on and off and it seems they can be had for ~$60-80/ea on sale.

Brake dust shields- 4runner p/n 47781-60140 (passenger/right) and p/n 47782-60140 (driver/left) respectively. At least one post saying they clear a gusseted spindle (no link handy, sorry, I believe the poster stated it was a wheelers offroad gusset kit).

I will likely just trim the tacoma dust shields to fit, and bend/adjust as necessary for clearance.

Brake pads- longest list/most questions here

-4runner OEM p/n 04465-60320 Basic oem pads, will likely have better braking performance than tacoma pads just due to the increased rotor diameter/increased torque. ~$80/set

-4runner TRD Ceramic pads p/n

$163 PTR09-89111 Toyota Genuine Parts - TRD Tacom Brake Pads (PTR09-89111)

PTR09-89111 Crashnburn80 had good things to say about the trd ceramic pad for the tacoma calipers, and it was his recommendation at the start of his thread- however there are reports of early failure due to the pad material splitting from the backing plate. Who is to say how common that is, but it does make me pause. ~$170/set

-EBC brakes "Yellowstuff" p/n

$113 DP41657R to Fit MITSUBISHI,LEXUS,TOYOTA (AUSTRALIA AND NEW ZEALAND),TOYOTA,TOYOTA COMMERCIAL

DP41657R
EBC touts this as their heavy duty truck and SUV brake pad, with noise and dust rated as similar to OEM, but "great for towing/heavy loads and oversized tires." I have never run EBC series oads on any of my vehicles, so I have no experience with any of their products. ~$130/set Looking for any input anyone has, Tacoma or not, with EBC's brake pads.

-EBC Brakes "OrangeStuff" extra duty brake pads. P/n ED91657
Ebc claims less brake fade across temp ranges. These have noticeable less of a chamfer than the yellowstuff pads, I'm assuming there could be a noise difference.


Brake lines-

I was looking at SOS performance stoptech extended braided lines for the front, but @reymataco seems to be having issues with his. Any suggestions for another maker?

Rear lines, was going to add Toytec's +2" extended braided lines p/n SS-20-05.

Any opinions on brake fluid? I'm at 53k miles and about 2-1/2 years of owning the truck, so I just decided the push the fluid change until I upgraded brakes.

 

Update, ordered EBC yellowstuff pads and the black zinc coated, slotted USR rotors from stage3motorsports. The high carbon rotors appeared to be out of stock everywhere I searched. Stage3ms had the high carbon rear rotors, unfortunately not the front.

Getting tires mounted on some 5th gen SR5 take off wheels on Monday. So when I get the extended brake lines I'll plan to do the swap, should be next weekend.

Edit- ordered motorcraft manual trans fluid and a set of dynamic friction calipers, instead of OEM. Supposedly new, haven't found many reviews, so I guess I'll take the plunge and post my thought on how everything comes together.
