:flamesuiton: I have to get all the Toyota stuff off my truck if I ever plan on getting parts for it in a pinch and the brakes are about it.

What is the most painless setup that will give me some stout brakes?

Alot of the Jeep guys are running '68 Vette master cylinders (4 wheel disks) for manual brakes without boosters. They say they stop really well. Go search the General and Jeep sections for all you really care to know about what works and what doesn't. You will have to filter out the crap that most of the posts are filled with.

1987ish S-10 Master with no power assist.

You'll be glad you did it!:D

OK.....manual brakes with an automatic? I have heard this but could it be true? Is this what I want?:confused:

4L60E and an ATLAS....this bitch pushes right through the brakes at idle!

Rugburn,

What is the status on the windshields? Sorry I did not call you back, I was out of town until yesterday!

Anyone have a good solution using hydro boost? I'm sure I'll be faced on the same problem when I get my D60's and Atlas installed.

I installed a booster & master on my friends' 97 chevy z71. that thing has LOTS of assist & stopping power, but might take some fab work attaching it to the pedal... thats just a thought, I don't know of it being done into a cruiser though. dimensionally it should work.

well i'll be doing it in the not so distant future. when i get the fj40/buggy project going, my hydro-boost setup from my jeep will be going into it. the hydro-boost kicks arse!

What happens when the engine dies?

One of the guys that was with us this weekend had his p/s pump die on his TBI-350 on the back side of some God-aweful mountain.

What the HELL would he have done if he had a Hydo-boost? That is not an easy pump to fix and leaving your 30K $ rig overnight while you go get parts would suck.

I am real torn because I hear the hydro boost rocks.

Good point, but how is that any different than a truck with a Tuned Port Fuel Infected motor? There's a lot of stuff that I don't want to carry around with me and I think Hydroboost is pretty reliable in comparision... TBI is slightly better, but still not butt ass simple like a carb. The 4x4 community has gotten way into complex stuff in general that is hard to fix in the woods. No thanks on either for me.

Just my dumb ass opinion , so don't get bent.

Yeah, I have wished for the forklift motor a couple or five times during this "shakedown" period myself.

why is a hydro-boost pump hard to fix? it is the same as any other. yes it does have an extra port on the pump but some people just use a t-fitting on a non-hydroboost pump so they don't have to change the pump. hydro-boost brakes work like a vacume style does with the motor off. yes i guess you could toast a pump but you still have brakes. they are just not assisted.

here is what i ask, have you ever heard of someone who is running hydro-boost complain about them? it seems there are some negatives people seem to point out but do they run hydro-boost? ask from the people who run it and ask for thier experiences. same with anything on this board. i try to look and listen to experiences from people who actually run the stuff rather than what people think it'll do.

Just bring a spare pump. They really are not that big.
And if you are really concerned about size just bring the internals. Get one from a junkyard (I know it will not be quite as good) and keep it handy.

Actually with all of the computer stuff you now have on your rig the PS pump is the least thing I would worry about.

There really is something nice about the simple tractor motor.
And the weight helps too :flipoff2:

I've been considering Hydro-boost also. When I do it I might run a seperate pump just for the brakes and leave the power steering pump just for the steering. I know it's redundant and takes more space but seems it would be easier on both.

I know my poor P/S pump has a hard enough time as it is, so I've shyed away from hydrobrakes.

Plumbing them might be interesting given the now heavily occupied engine bay in Kate...

And really, I don't see hydrobrakes being the end-all-be-all.. IIRC, it was created to adress the problem of diesel engines not having vacuum in the intake, wasn't it?

Since you have a FI'd, auto tranny gas V8 (read: near-unstallable), I'd either go vacuum assist or manual.. I'm a carb'd, manual tranny.. and I stall it alot. I need to know that I'll have brakes, even if I have to back it down a long hill after my dumb ass stalls the motor and it won't re-fire because if the angle.

Tell ya what, you can borrow my cruiser, and I'll drive yours and figure out the problem, fix it, and give it back... deal?

Sounds like a deal :flipoff2:

Brian, you are right.....I hear great things from Hydroboost from those that run it. I just need to do some thinking on it is all.

Eskimo pointed me toward some real inexpensive GM booster/masters that I think I will try first and save Hydro boost for later.

Do either of you care to share this with the rest of us?

Nolen's giving me too much credit... I found cheap master's, but boosters are $$$

let me know what size bore ya need, and I can point ya to the right master cylinder.

Eskimo,
Somehow I think you would be getting the short end of the stick, we all have seen what Nolen does to a rig he owns... imagine what he would do if he did not have to pay the repair bill!!! :eek::rolleyes: :D

Nolen,
keep us up to date on this booster thing, I sure could use a little extra stopping power.
