Let's talk about Hydroboost Brakes (3 Viewers)

[scrapdaddy]

I need a new project and hydroboost brakes sounds like a good idea. I know J Mack and Megadoomer are running them, so maybe they will tell me again what make hydro they're using. Wish I would of written it down the first time. I'd like to upgrade the brake power to all 4 disc and would like to buy a new booster and master cylinder, so what should I look at? GM, Dodge truck, etc. For the master cylinder i'd like to buy Wilwood, any thoughts.

Thanks!

I had a Ford setup on my Rockcrawler but it had 40” tires and about 500 hp.

What’s happening with your setup that you feel the need for hydro boost?

 

[Megadoomer]

2002 GM 3500 Hydroboost and MC was $100 at the junk yard. Grab the tubes because they should bolt right in to your current power steering pump. You may need to change a fitting for where it goes in to your box. I think you have a 60 PS box? This setup turned my stopping from that of a freight train to a Honda Civic.

It's not stopping as quick as I would like and I like projects.

 

[wngrog]

Of all my Cruisers I agree the 55 stops the slowest. I just did a complete brake job and dialed in the rear drums and it’s still pretty weak. Curious (other than weight) why that is. My 60 is heavier and it stops way quicker.

We came down Monarch Pass coming home from the Pig Party and smoked the brakes pretty bad. Admittingly pulling the military trailer without the trailer brakes working, but I want the best stopping power I can build.

I know J Mack

Any GM style 1 1/8” master cylinder should do. I used this one, Baer Brakes Remaster Master Cylinders 6801266LP

I believe most of the truck hydro boost units are similar with mounting plates and pushrods being the main difference.

That's the hose I'm using now and have the PSC pump, so everything should play well together.

So, you like the Baer master, any opinions on the Wilwood master.

 

[scrapdaddy]

I think you have a 60 PS box

Thanks to Deo, I'm running an 80 series box.

So, any GM truck hydro will work.

Wait, what? How hard was it to make the 80 series box work on a FJ55?

 

[J Mack]

So, you like the Baer master,

It’s bling, chicks dig the bling…

Although it hasn’t helped me win any show and shine competitions lately.

any opinions on the Wilwood master

Not as blingy..



Might as well save a few bucks and buy this, The Right Stuff DBMC01 1.125 Inch Bore Master Cylinder, 1970-79 GM

So, any GM truck hydro will work

AFAIK.

have the PSC pump

As long as you have the Remote Reservoir with three fittings on the bottom its easy peasy.

I'm all about the bling. You got to have straight door panels for the Show and Shine.

I was already running a 60 box, so just a bolt up.

Lil' John,

From what I've been reading the hydroboost is a far better system than vacuum which damn near doubles the pressure, if not more. I also have a hodge podge mix of Toyota parts, but the disc on each corner are all 4 runner stuff. My brakes work, but not where I'd like them to be.
