Now that I got your attention.
The master cylinder in my '88 Yota 4x4 is in the way of installing my new King Shocks. I thought of doing away with the power booster, mounting a M/C direct to the firewall to give me the room. Has anyone done this before?

Well, anything is possible with enough fabrication.

The pushrod may be designed to have that extra 2 or 3 inches of booster there, so it may need to be cut down. Other than that I would really worry about your brakes working well. Try disconnecting the booster or just rolling and trying to stop with the engine off after the vacuum has bled off... unless you're the iron man, I wouldn't want to try to stop it with unassisted brakes.

Here is what I have come up with so far.
I first thought about building my own ôhydra-vacö system by moving the existing M/C with booster to the passenger side. I would have to cut out the "A/C hump" in the firewall, plate it, mount the brake unit inside the cab leaving the "pedal rod" sticking out into the engine compartment. Then fabricate a mount for a clutch slave cyl to operate the brake booster. Then adapt a second clutch master cyl to mount in place where I removed the brake booster from to act as a brake M/C.
Result:
Foot operates pedal > operates new clutch M/C > operates slave > operates booster > operates old M/C > operating brakes, all this to give me the clearance to install 2.5 x 8 King 2 tube bypass shocks on a modified front IFS.

Think it will work? I thought it pretty ingenious myself but a WHOLE lot of work.

I then called CNC and checked price on a dual M/C set up. OUCH

Now I was hoping someone out there had a cheaper way of doing it.

Anyone know who makes an offset mount form booster to m/c?

Ever considered hydroboost brakes?



Uses the power steering pump to hydraulically boost the power brakes, rather than using a vacuum booster and diaphragm... Should be easier to modify lengths as needed.

i don't think eliminting the booster is a good idea

i build brake training simulators at work
we use a vacum pump for the booster and if you leave the pump off you get maybe a 1/4 of the pressure than if the vacum was on

with the vacum on i have seen a few of the system reach around 2500 pounds of preasure and with no vacum barely reaching 500 pounds

if i was going to install those shocks i would have to find another way to install them or go with a different set of shocks
