My brakes are in desperate need of replacing (front pads at least), but I'm wondering if it would be worth doing an upgrade. I tow my vintage travel trailer (~2000 lbs) with it, so a little extra braking power wouldn't hurt.
I know there's the TRD big brake kit, but I don't know that I want to spend ~$1800.
Amazon has some Power Stop kits that are reasonably priced for upgraded rotors and pads https://www.amazon.com/dp/B005FKS28C/_encoding=UTF8?coliid=I3PUEQQLDRWUF0&colid=1BU4RYDDHQPIX&psc=0 and they have pretty decent reviews. But I know you're not "supposed to"" use drilled rotors off road...
What have you guys used? Again, looking for more stopping power, especially for towing, but would like to keep it under $1000, or better yet under $500.
Is there any benefit to upgrading the rear brakes on our trucks? Seems like for towing it would probably be more helpful than under normal conditions. Thanks

Slotted rottors and better pads will do the trick if your trying to stay around $500. Even without towing u already have more leverage on the stock brake components adding a larger diameter tire than stock. Im currently running EBC sport rotors and ebc green stuff pads on all four corners along with stainless steel braided lines . To put it in perspective on the stock system coming down big bear resort. A lil more than half way the fj was experiencing major brake fade on stock system. After brake swap it could make it to the base of the mountain with out fade. However after driving my friends fj with the trd bbk, the bite and pedal response is soo much better that im wanting it. I know your running 17" wheels brian so another option is s.o.s performance they make a 4 or 6 piston bbk. Also u can piece a new bbk kit for cheap by getting rotors and caliper from lexus. Mounting tabs for caliper are the same as fj but it has bigger pistons. Rotors also have a bigger diameter. With 17" wheels u have clearance.

Thanks for the info Josh. What Lexus year/modle should I look for brake rotors and calipers off?

Ur best off with the 5th gen 4runner brakes...direct replacement

Stock fj front brakes
Rotor- 319mm x 28mm
Piston bore- 45mm

5th gen 4runner
Rotor- 338mm x 32mm
Piston bore- 48mm

U will need front calipers, oem dust shields, rotors, pads.

Highly recommended you also get stainless steel braided brake lines.

Calipers you can get at rockauto, amazon, other parts stores. They are the oem remanufactured and will come in a bare finish so highly suggest you paint them w/caliper paint to avoid any surface rust to develop.

The part numbers for calipers and oem dust sheilds are as follows.

Centric (sister company to stop-tech that makes high performance brakes including the TRD bbk.)

Calipers:
141.44287
141.44288

Toyota dust shields:
4778260140 left
4778160140 right

Stainless steel lines
All-pro
5500fjt-ap-f. Qty:2
5500fj-ap-r. Qty:2

Stop tech
950.44507. (Also for the rear attached from disc to axle mounted brake lines)

Rotors:
Ebc brand
Gd7578

Stop tech (centric) brand
126.41174sr
126.44175sl

Brake pads u can go with:
Ebc yellow stuff
#dp41657r

Hawk
#hb490y.665

Since u mentioned towing those pads should work.

Hope the info helps brian.

Following pics are the extended brake lines on my fj.

Thanks so much for all the great info Josh. I'll add up all those parts and see how much it would be to do that conversion, vs just rotors and pads. I'll report back.

U got it brian. It should run around $650 if you shop around which is a heck of a deal for technically a bbk. With rotors coming in above 13in diameter. I have no choice but to stick to the TRD bbk since im not getting rid of my 16" wheels anytime soon. Take advantage since you have 17" wheels.

Is the master cylinder okay despite the larger pistons in the front calipers?

I've done the stainless lines, more agressive pads, etc... I still got massive brade fade going down Angeles Forest/Angeles Crest Highway for 10 miles. It was SCARY! I'm in the market for larger brakes myself and have looked into these options:

Stoptech 6 piston BBK for $1,638 after the 20% discount: https://sosperformance.com/products...a-tundra-e085cd65-f078-490b-81ad-8e80dcf80e07

Or

The Wilwood's 6 piston BBK for about $1,750: Wilwood High Performance Disc Brakes - Front Brake Kit Product Number: 140-14577-DR

 

[mk-Zero]

Thanks for posting those options 383. To me, I don't know those are worth the extra money though... the StopTech kit uses the same size rotors as the 4runner option, and the Wilwood ones use the same size rotors as the stock FJ ones. Basically you're paying for more caliper pistons.

Seriously looking at this upgrade kit for my 2008 FJ. I looked up the part number for rotors but they show 5 lugs instead of 6:
Ebc brand
Gd7578
Is that still the correct part number?
