My 2006 Tacoma brake upgrade (EDITED!!)

Yes he did, my bad....

 

You guys are the best. I along with others yet to do this upgrade are very grateful for ur hard work

 

Upgraded to larger rotors last year, brakes still sucked, had to pump once like someone mentioned to make them better..found this upgrade while looking up rear discs.. bought everything for around 200 bucks, what a massive improvement, should have been this way stock! Could feel the difference before I made it out of the driveway!, was easy to do, no big deal, was able to bleed brakes from master to abs unit, with no air no spongy brakes, best information i ever got from here, I used to drive my rusted out 1993 4runner to pull my trailer because I felt safer stopping it than my Tacoma, cant wait to pull something with this upgrade, great post!

 

Nice I’ll link to this from my post on To T4R setup. I can’t upgrade to the tundra/sequoia but looks killer you got it all working.

 

Thank you and I feel the same way about this mod. I had to share it.

 

nice! if/when I am up to it I am going to look into the 2010-2014 4runner Electronic Master ATRAC etc as a swap into the Tacoma Off Road/Pro's that can't upgrade but only if I can find a good donor those things are $$$$$$$. I have a 4runner rear disc conversion as well. since you got this setup you can then upgrade the BBK up front with ease.

Another recent one thats plug and play for dual diaphragm is is the new camry's bolts right up. Not sure if you have seen that one yet but looks to be able to bolt up without any welding.

 

I still have 'stages' in pump performance on this setup. The first usual press requires a little more distance to start working, and of course works better than my stock booster did, but pumping once first (like I did for over a year before) still wakes the booster up even more and require much less pedal distance to start working.

 

Interesting. My brakes don’t require any “pumping” action right now. The pedal still travels about as far as it did on the stock calipers before engaging but after I fully bled the system, it’s consistent every time I go to stop.

 

Yeah, my Taco is up for her 120K service this weekend, if a brake fluid flush isn't part of that, I might ask for it ($149) - they pressure bleed the system. I had my neighbor help me, done the 4 wheels in proper order....then done another round of bleeding and found air again. I hate bleeding, lol

 

It took me three attempts to get all the air out of the system. Twice, using the Techstream to bleed the ABS system. But the real key were the speed bleeders I installed on all four corners. Without them, we just couldn’t keep air out of the lines, even with a vacuum bleeder.

 

Ok i must have gotten lucky, no air, no pumping, i bench bled the master then at the abs unit, then wheels, drove it about 75 miles today, stops so much better its like a new truck, actually finding myself stopping early/too soon for stop signs, so much better. Big question, has anyone who's done this drove in winter conditions with it? And if so how did it perform?

 

My stock Tacoma brakes did the same thing and so does this upgrade does the same thing now. I don't know why. I'm guessing it's the ABS because I've never experienced this "problem" before and I've also never worked with ABS. However, you wrote that you go to each corner.... are you using a Techstream or??? because without cycling the ABS I personally don't think it's possible to get all of the air out. When I first put it together I was amazed how well it stopped, but I could pump the pedal a few times and it would get better. I put a lot of effort into bleeding it in my driveway and the shop that finished the air bleeding job did get more air out of it.

SomewhereI read I could unplug the ABS electrically and in essence turn it off. Man I'd love to turn that ABS off.

On my truck it's not so much pumping, it's more like you stop at a red light and just lift your foot off of the brake pedal for a second and put it back down and the pedal is higher off of the floor the second time around.

I bet a shop could get air out of it - no offense meant

I live in So Cal, not exactly winter conditions, however I did drive it in heavy rain on a freeway that hardly ever sees rain (lots of oil on roadway) and it was still amazing until a caliper bolt fell out and the truck did donuts on the super slick blacktop.

I love my trucks brakes.

 

for those wondering, this particular shifter extension worked out perfectly for me. Screwed it onto the booster all the way with the Tundra nut to lock it in place, then the tacoma clevis onto it all the way with a lock nut. Measured, it was within a 16th inch of the original tacoma one. No all thread, no welding, just screw it together.

And yes, the EBC 4runner brake upgrade with Tundra booster/master works great. truck stops hard now, I can hear the tires really biting on a hard stop and I still have lots of modulation to go. Old brakes didn't even do that at all, they were down right scary to stop the 35's and a heavy expedition camp rig... I'd bet I still have some air in the system though, pedal much softer than expected - but it may get better when the brakes are fully bedded in.

You folks talk about bleeding at the ABS unit, care to explain? I'm not a fan of breaking flares loose to allow fluid out, and not aware of a bleed port up there in the engine bay. I did bench bleed the master by looping hoses back to the reservoir, pushing the piston till no more air came out.

 

Awesome.

There's something about the ABS needs to cycle electronically in order to get all of the air out of it, idk, I took it to a shop to get the air out that I couldn't get out of it.

 

My 120k service was done last week and they went ahead and pressure bled my lines again. All good now! Tech said 'nice job I did' Still have a pedal stage progression, but nothing new. First pedal push requires more length to start working, but pumping even a half pedal push first will engage the brake system after an inch or so which is incredible.

 

Update on booster conversion, freaking sweet, got to haul 2 ton to junk yard sat, (to trade for more toyota junk of course) stopped my trailer better than i hoped, smooth and powerful, running large Toyota rotors and tundra booster and master, stock drums, ...ended up finding a 2006 4runner rear axle,, rear discs, anyone swapping out drums for stock rotors? Can it be done?

 

SOS makes a conversion kit. there are a few threads on it. You will find mixed opinions mostly saying it’s not worth it but talk to the ones who have done it. I have a kit but have not installed it. My truck can’t upgrade the master so debating swapping.

 

I doubt that the people who tried 4Runner rear discs had the Tundra booster and MC and I'm positive that would make a difference.

 

I’m sure most are swapping in the sequoia master at least if they have a non ATRAC model. since I have the electronic master with ATRAC that’s not an option.

 

so this company makes a kit for the brake lines to hook up the Tundra MC and Booster and the Pedal . kinda pricey tho. also, they can make a complete kit with everything included if you email them. i havent but just thought id pass this along.
