NEW '97-'06 Jeep Wrangler TJ Power Brake Booster

This is a new (not rebuilt) hydroboost and mount assembly for a '97-'06 Jeep Wrangler TJ. It will bolt straight to your firewall using your existing bolt holes and requires no modifications to your Jeep brake pedal or the firewall. This hydroboost assembly uses a drop rod end (shown in the third pic) that connects straight to the lug on your power brake pedal and uses your OEM nylon bushing. The Jeep TJ hydroboost is centered in the mount bolt pattern allowing you to flip the unit upside down if you want to improve clearance to the engine by moving the accumulator to the driver side of the engine compartment.You can fit a short input '78 Vette 1 1/8" power brake master cylinder or if you are heavily modified and running the largest late model dual piston calipers you can bolt on a late model GM MC designed for those brakes and large enough for the late model Dodge/Ford calipers as well. I have guys running full hydro with no internal modifications ("flowing") to the hydroboost, even PSC's TJ 2.5" steering rams in combination with full hydro. You might want to ask me what specific hoses and fittings permit the hydroboost to be run without "flowing" it, some are more restrictive but with the right setup 4.5gpm can be run through the hydroboost. Check out a vendor of mine who builds full hydro 4 wheel steer buggies in Spain using my hydroboost assemblies with no internal modifications to the hydroboost, the videos are on my website. Google BadAspBrakes or CustomPowerBrake. Ask me for the link to a customer's full hydro and steering ram build on Pirate.Tech, info on building pressure hoses, and pictures of custom hydroboost installations as well as my contact info can be viewed on-line at CustomPowerBrake.***Regarding use of replacement return hose fittings on the booster: When the booster is inverted or clocked on the mount for clearance to the motor the return nipple points the hose at the header or into the inner fender depending on the vehicle and set up. If you don't use a banjo fitting there and use an AN-6 Spittier fitting then you need to know to before you install it to take a drill bit (or 0.110") and make sure it passes through the orifice before you use it and drill it if it doesn't. 0.110" is OEM ID for Bosch return fittings and anything under

size can cause slow pedal return.****Allow me to dispel some myths... There simply are no vacuum boosters that will give you the same dramatic increase in line pressure at the caliper that hydroboost will provide. The largest vacuum booster you could possibly fit would only give you about 1,700 psi at the front caliper and that is if you had room to fit it and the engine produced the vacuum it was designed for. If you have a low vacuum motor and a 7" dual diaphragm booster (like a customer of mine with a built 5.7 Hemi who tested line pressure with a gauge) you will only get 1,000 psi at the front and 800 at the rear calipers. You need about 1,600 psi up front for disc. After installing my hydroboost he tested it at what you can see in my last pic above. Got it? ;) Thats an increase of 1,400psi at the front caliper at idle. 2,400psi..... yes, your pedal will be lighter;) John's car is a '37 Plymouth Tudor and he hauls a trailer for his two Harleys. His comment to me after the installation of the hydroboost was "this thing could stop freight trains". Thanks for the testing, pics and feedback John! It's what dispels myths. Installing a hydroboost does not just make your pedal easier to press, ask anyone who has hydroboost installed. I have had a lot of customers tell me that swapping to hydroboost was the best modification they made to their vehicle and should have been the first. Think about it for a minute.... is it really going to help your braking if you switch from 11" disc to 13" and go from single piston calipers to four piston if you still are only going to have 1,000 psi at the front caliper when you need at least 1,600 psi? Yes, the braking would improve over what you had but you still don't have the line pressure and only changing the booster to hydroboost is going to give you 2,400 psi. To my knowledge, not even electric boosters will give you that much pressure and 2,600 psi is obtainable with the right master cylinder. Installation of hydraulically boosted brake systems will increase your line pressure up to a maximum of 2,600psi (as tested and I have a gauge reading to demonstrate pressure at idle) depending on the master cylinder you select and the other components in your brake system. Consequently your brake system must be in top shape to handle increases from normal 1,100-1,600psi. Many power brake master cylinders can be used on this hydroboost and the iron '77-'80 Corvette power brake MC is a frequent choice. ***Be sure the power steering pump you are using will be adequate to run with hydroboost which typically require 1,300-1,500psi and 2.5-3.5gpm. This hydroboost is not designed to be operated with power steering pumps exceeding 1,500psi. It is compatible with ABS. If you have a different vehicle you'd like to set up with a custom firewall mount just shoot me a message and I'll work with you if I think it can be done. The bolt spacing for the master cylinder is 3.4" and if you need a custom adapter to fit a 3.2" spaced Dodge or Ford master cylinder I have those available, and I have used master cylinders available also. Just ask....;) I can help you sort out what you need for your hot rod or built rock buggy using the largest dual piston calipers. I have set up C3 Corvettes, Chevy S10s, Toyota FJ 40s, Jeep Commandos, Wranglers, CJs, and the M715 as well as the full
