Doesn't look possible to squeeze it in, anyone done it - any info on this swap? I'll be running a D60 rear/44 front

I don't think you need it unless you have a wimpy leg. I'm using a stock single reservoir master cylinder with chevy disc brakes front and rear and it works great.

I agree with Ben. In Rock Scout (65 Scout 80) we used a Stock Scout II MC with no booster. After wheeling with Ben and having to two foot the brake to get it to stop, I would say stay with the stock MC. If you really wanted to boost it you could try and inline booster between the MC and the block that bias front to rear.

interesting.. I'd think at the minimun you'd want to go to a dual but hey.. if it works..

BTW this will be a highway driven DD on 37's

IMO for manual brakes, single res master cylinders have better feel than tandem circuit. If you want redundancy so you don't lose all brakes if you blow a line, look at one of the racing setups where they use two independant single circuit MCs. Like this (http://www.speedwaymotors.com/xq/asp/strBase_List./hilt./source.2191/base_no.91029975/str_base_no.000%2DCATALOG+RACE%2C8353401290%2C9102 9972%2C91029974%2C91029975%2C91085110%2C91641025%2 C/header_title.Race+Products%2DPedals/page_name.prod%5Flist%5Fdisplay%2Easp/search_type.L2%7E17/search_option./deptsearch./deptSearch_id.2/dept_id.L2%7E17/dept_id_p./dept_name./dept_name_p.Race+Products/ShowImages.yes/sq.0/cont.1/intPgNo.1/redirect./qx/product.htm)

I had a vette MC on my jeep with 4wheel disk before and it worked great, I might try that setup again.

80's Mustang I was told works. I used SII but I made the inner fender fit around it... :smokin:

I know the vette MC works, but I don't see any advantage over the stock MC.

I thought someone here or on the BB did it, or had hydroboost, or some such. I remember they notched the wheel well to make it fit.

Thats an aftermarket unit like a TCI (Total Cost Involved) but its by mike somebody. Its close to the fenderwell but its got about a 1/4" of clearence and the hood fits fine. I used a stock brake pedal assembly and used a flat 1/4" steel plate to connect the two. It works Great

EDIT: Also, the wedge backing plate was moved up one bolt hole and re drilled. and some extra fab work was needed on the brake assembly to get it all to fit but its in there.

I have herd the SII MC will work (with mod) for 4xdiscs but I was unsuccessful. Vette MC was the best alternative

Go to the boneyard and check out some vans, specfiaclly dodge vans. They are mounted 90 degrees to the firewall and would solve the Scout mounting issues. For bonus points find out what chevy did for their diesel vans, Might be a 90 degree hydroboost setup. That said don't bother with a booster, you don't need one with the long Scout pedal and a well thought out system. It's nice to not have to worry about brakes should you stall or need to get dragged off a trail non-running.

I've got a early 70s Mustang MC, which had 4 wheel disc brakes.
It is a double res., one being larger.

Works well, & no need for a proportioning valve.

I'm with the other 800 owners. Snoopy NEVER had power brakes and NEVER needed it. I was running D60/D44 combo with 4-wheel disc brakes, and my wheels were modified Hummers w/ 38.5" rubber (together they weigh about 120# per wheel) and I could lock those babies up at a moments notice.

The big benifets is that if your engine stalls, the brakes work the same as normal.

The MC I used was from a 68 Corvette w/ manual brakes (they came with discs f&R) ~ cost only about $45! (no core)

The dodge 90 degree booster is a no go as the steering column is in the way. Look at Buckshot33's pic. The column passes through the hole to the right of the booster.

As for any chevy options I can't say?

I am planning hydro-boost on mine...

Buckshot33-do you have a part# on the booster/master?I like that setup! Thanks...

yeah I'll get a p/n and take a pic of the pedal/plunger assembly under the dash too because it needed to be "augmented"

I've built about 6 hydros for these setups. Have 6 happy customers, they all had to make their own lines though.

You dont need power brakes.
Just downshift and stomp.

You might look at camaros and firebirds, and maybe other cars. I believe the booster/master is angled up slightly, might be enough to clear the fender. I'm pretty sure the cadillac hyrdroboost was also angled up. I would just hit the junkyard with a tape measure and find something that would fit, or make something fit.

For bonus points find out what chevy did for their diesel vans, Might be a 90 degree hydroboost setup.

It's not a diesel, but my parents motor home (based off a 76 Chevy G30 van) has hydroboost. It uses the typical setup like the trucks.

Ok, Speaking as someone who does have one of those, is hydroboost the best choice? I was going hydroboost, and I belive it is the better choice, but I'm open to suggestions

Would anyone be kind enough to post a pic of their hydroboost setup on an 80/800? I'm kinda in the market for one (or any Scout) and would like to check out what you did. Just figured I would throw that out.

For the power and fluid hydroboost is the way to go. Their expensive though, by time time you're done with the conversion you'll be down about 700 bucks (buying through me). Cheaper if you junkyard it or build your own. I have no pictures, customers never sent me any.

Brandon
10-20-2004, 02:42 PM
the question is - will it fit without cutting out the fender? I guess cutting it out isn't a big deal but a clean install is nice..

Total length of my scoutII conversion was 15".
Not sure if it will help you.
I have the pics and write up here. (http://www.justinternationals.org/Binder-Bench/showthread.php?s=&threadid=2785)

This is where you'd come in, I'd need to ask questions to verfiy. The system is 4.5 inches thick, no thicker then the m/c and 14 3/4 inches long. We can also tilt up or tilt down. I'd basically get you on the phone with a tape measure and barrage you with questions;-) The Scouts I have done have had 0 problems. Scout IIs.

If the firewall angle is an issue, how about a pair of axle pinion shims. You could set the angle at what you want and if you used steel, they can be tacked in place for added safety!


I just completed my whole setup for about $70. I bought a new MC resevoir because the original had a crack.
