Need a short master cylinder.

SOn my 85 Toyota.



With shock mount finished the shock sits right at the end of the current cylinder which does clear. Problem is that cylinder is too small to work with my new brakes. Most people doing tons on these trucks use a T100 Toyota booster, adapter, 80's chevy 3/4 master....problem is that combo is about 2-3" to fit where i need it.

So my question is where can i buy a short reservoir 1"+ bore master cylinder? Don't care if its aftermarket or oem off something else. So far all i have found is a flame covered billet unit from ssb for 587$ which is way out of my budget

Do you have the single or double diaphram booster on there now? What part of the combo is too long, when you say the T100/3/4 ton combo is too long?

You can get Toyota masters at 1" and 1-1/16" and more.

Right now i have a single diaphragm booster....all signs point too it not being good enough for bigger master. The t100 booster is dual and is 1" thicker and will work with a bigger master from what my research is saying.

As far as the master....i am running 80's f350 discs on the front and 80's chevy front discs on the rear so i need something to move enough fluid for that combo. I will have ~7" from booster surface to the shock hoop to fit the master and any necessary adapter.

I actually ordered a 2010 camaro master a little bit ago....it is super short and supposedly mounts the same as other gm applications...if this is true than problem solved

I may be missing it in my search but where are you finding the larger bore Toyota master cylinders? I would think they would also work if they are compact enough so i didn't have to adapt the gm unit

Most of the mid 90s stuff used 1" bores in them, like regular T100s, land cruisers, some 4 runners, etc. The 1-ton T100s use 1-1/16" bore.

I used a dual diaphram booster from a late 80s Supra, but the ones from later trucks work fine. I've heard that if you go bigger than 1" bore, you really want the dual diaphram booster.

With mine, I had IFS front rotors, late model 'V6' finned calipers, on the rear I had SA rotors and calipers, with the supra master/booster (1" bore), and it would easily lock up my 38.5" Swampers.

From another thread (for Toyota MR2s, no less!)

tacomas are all 1" bore, match ABS/non-abs
mk3 supras are 1" bore, all are ABS style.
94-95 SR5 4runner ABS thru 10/95, 17/16" bore, abs style (this is the largest MC available that fits the MR2. the pedal gets REAL stiff with this one)
94-95 4runner, T100, tacoma non-ABS, 1" bore, non-ABS style.

Thanks!

I have a T100 dual diaphragm booster on its way that i bought off ebay.....the Camaro master cylinder will be here end of the week so we will see how that works.....if it doesn't your info gives me more options.

I am a little leery of something like a Tacoma master cylinder only because the Tacoma guys running one tons all complain about spongy pedals and usually go to the chevy setup....but i don't know if it actually necessary or if they are just over sensitive.

If you don't mind moving your gauges around a bit a 90 degree setup should give you enough room. If you have heat you will need to move the ducting and make sure you have enough room to get around your steering shaft before you begin. But, it may be a option to help clean up your engine bay.


Here is a expensive one through kugel to give you an idea. I believe speedway sells a cheaper one or you could just make your own.
