is v-6 calipers the same as 4 cylinder ifs calipers ? i got 4 cylinder on my truck and they are weak brakes.

no they are not the same. v6 calipers are much larger and hold more fluid. the v6 calipers will bolt right onto your knuckles in place of the four cyl calipers

so if i get v- 6 calipers you think that well fix my problem of my front brakes not locking up . now ive got a chevy master cylinder and rear disc brakes. my back brakes lock up but my front want.

pumkin toy · « **Reply #4 on:** Nov 22, 2009, 03:14:28 PM »

yeah that may help but it sounds like you could have a proportioning valve problem if your rears are locking up. also if you get v6 calipers you will want to run vented rotors off of an fj60 with them.

well i just did a sas on the truck it came with venter rotor in the kit and i just put the 4 cylinder calipers back on the front they came off the old ifs front end

get some v6 calipers and a brake proportioning valve from some place like Jegs or Summit

Depends what year your truck is. After 90 they all came with the same calipers.

What kind of calipers are they on the rear? If they are bigger then the front capilers you will have that problem.

Go to this thread on PBB and it will explain it better. Go to page 6 and down to post #136 and read from there.

HUH? i dont think im gonna be doing a rear disc "upgrade" anytime soon

Forfunner · « **Reply #13 on:** Nov 22, 2009, 10:50:46 PM »

Quick question. FJ60 and FJ62 are the same disk right?

Cheesemaker · « **Reply #14 on:** Nov 22, 2009, 11:03:56 PM »

Should be, since the big difference is carb (fj60) and efi (fj62).

Don't you turn the valve in to lessen the braking pressure to the rear?

bng1 · « **Reply #18 on:** Nov 23, 2009, 01:32:54 PM »

does anyone know if the 87 and up Toyota V6 Calipers are the same as the 90s and up Toyota V6 Front Brake Calipers??

emsvitil · « **Reply #19 on:** Nov 23, 2009, 01:34:20 PM »

86 didn't have a V6...........

motoracer · « **Reply #20 on:** Nov 23, 2009, 02:20:58 PM »

yes you turn the valve to lesson the pressure but its turned all the way down

SQUIRREL MONSTER · « **Reply #21 on:** Nov 23, 2009, 05:43:15 PM »

slightly relative topic but, arent the 4runner and v6 pickup rotors the same as fj60 rotors??? or can both of them be used??

2manytoys · « **Reply #22 on:** Nov 27, 2009, 02:07:18 PM »

You guys got me considering a caliper upgrade for my 1988 pickup now. Mines stock with 22RE.

I know the V6 calipers are supposed to bolt right on. Are there any clearance issues with 15 inch wheels? I have 31/10.50/15's on cheapy chrome modular steel wheels.

How about the master cyl and booster? My son's 91 4 cyl pickup has stock brakes and stops WAY better than mine. His truck has a dual can booster. His truck can put you through the windshield with little pedal effort. Mine feels like non power brakes compared to his.

Would I be able to bolt that type booster/master cyl on in combination with the V6 calipers for major braking improvements?

There is a lot of misinformation out there. Is it true that 93 up 4Runner brakes would be the parts to get?

i got v6 calipers on my pickup and only issue i had was the dust shild had to be trimed so they could bolt up,as far as the wheels i got a 1"1/2 wheel spacer and i have no issues for clearence .ive got a stock booster and a chevy master cylinder it does stop good with 35s just my rear lock up before my front,the only thing i dont like, but i do have rear disc. i could teel a big difference in stock 4cylinder calipers and v-6 calipers

you will probly have clearance issues without wheel spacers but yes the v6 calipers will bolt right on. I used a v6 4x4 t-100 brake booster on my 84 pickup. it bolted right in and made HUGE braking improvement, along with the v6 calipers and 1" bore MC

Nope, rotors are different.

It varies wheel to wheel, offset and design being the factors I believe. Aside from matching the rear width, it's another reason some run wheel spacers.

2manytoys · « **Reply #27 on:** Nov 28, 2009, 04:31:31 PM »

Thanks for the info. I'll be swapping on the V6 calipers when I need my brakes done. Maybe the dual chamber booster too if I can get my hands on one. Hopefully, I won't need spacers.
