About Sweeting Performance
We specialize in performance power brake systems, particularly the Bosch Hydro-Boost®, Bosch Hydro-Max®, Bosch iBooster®, and our own Air-Hydraulic power brake system. George Sweeting was an engineer for Lockheed during WWII helping to design brake systems for airplanes, he started a small brake rebuilding shop, Power Brake Service, in 1950, his son, Bob Sweeting, built the company up, rebuilding mountains of brake boosters and master cylinders, as well as working on and designing brake systems for many notable clients and projects. The owner, Matthew Sweeting, is the third generation leading the business in designing new retrofit braking systems for individuals with specialty vehicles and small volume new vehicle manufacturers. A fourth generation, naturally crazy about cars and planes, helps and is learning about advanced vehicle brake systems.
Matt was rebuilding brake boosters from a young age - tearing down, buffing, washing, painting, stocking, installing, sourcing, and the general business of brake parts. Being a third generation brakeman meant being taught the right ways about brake systems, new and classic, and having a natural familiarity with these systems from taking them apart and putting them back together repeatedly. The rebuilding market changed, volume and low cost became prioritized, and it has changed again, more recently, in the aftermarket toward new replacement parts that are sourced from the cheapest place they can produced, where quality has never stopped being our focus. Brake systems for new OE vehicles are getting very complex, with computers, electric motors, switches, sensors, and accumulators being added to a once fairly simple master cylinder. We now we work on lower volume, more complex braking systems, sourcing original replacement parts as much as we can and then designing retrofit replacements using new OE parts and/or manufacturing them ourselves, rather than rebuilt, when supporting the original system becomes unreasonable. We can offer many new replacement parts, where the factory or parts store will call them obsolete, we either have already designed, or can design a new upgraded replacement.

The Bosch Hydro-Boost®:
The Bosch Hydro-Boost® is what we use most often for applications from sports cars on up to 1 ton Ford F350's and GM and Ram 3500 series Trucks. It is smaller than the ubiquitous 7" hot rod booster and can generate 1200 to 2000 psi at the calipers. It accepts master cylinders from 15/16 inch to 1-5/8 inch bore sizes. We stock replacements for vehicles that came with Hydro-Boost® from the factory, but also make kits to adapt the Hydro-Boost® for retrofit on vehicles that were originally unassisted manual, vacuum boosted, or electric-hydraulically booster.
The Bosch Hydro-Boost® is powered by pressure from the power steering pump and requires no vacuum, whereas vacuum brake boosters are usually powered by the vacuum created by your engine manifold. You hope to get 15 pounds or more of vacuum from the manifold, but if your engine is not producing vacuum, typically because of a larger cam shaft, supercharging, or you have a diesel engine that makes no vacuum, you might try to chase vacuum with a vacuum pump or use a small bore master cylinder to spike up the pressure in the line. Customer feedback over a long time says that vacuum pumps do not keep up, are noisy, and burn out too quickly, and small bore master cylinders leave you with too long of a pedal throw because the volume that is needed to fill caliper pistons has been reduce. Big expensive caliper upgrades, will be more demanding of volume and pressure, not less, so reducing the volume that your master cylinder pushes by using a small bore master cylinder, and reducing the pressure in your line by going manual are the wrong direction to go in. A more powerful brake booster, like the Bosch Hydro-Boost®, will assist you in pushing on a correctly sized master cylinder to get the right combination of pressure and volume of fluid that your calipers need for good braking and a good pedal feel.
The Hydro-Boost® has a smaller footprint than most brake boosters, so fits almost anywhere a vacuum booster does. It provides great valve cover clearance, and exhaust pipe clearance when frame mounted. You have some options for customizing your kit, like choosing stainless braid PTFE vs. high pressure rubber power steering hoses, or a more stock looking master cylinder vs. a higher end Wilwood master. We have many direct replacements, our own kits for retrofit applications, and design new applications all the time.
Our popular Hydro-Boost® replacement and conversion upgrade applications are:
• GM Trucks • Ford Trucks • Dodge Ram Trucks • Toyota Trucks and Land Cruisers • Land Rover Defenders • Diesel vehicles that came with vacuum boosters and vacuum Pumps from the factory • Jeeps and Other Off-Road Vehicles with larger tires and axle swaps • Cadillacs • Jaguars • Buick, Pontiac, & Oldsmobile, especially G Bodies • Ferraris / Lamborghinis • Panteras • Muscle Cars - Chevelle, Camaro, Corvette, Nova, Tri-Five, Impala and other full size Chevy, Mustang, T-Bird, Crown Vic, Torino, Cobra replica, Charger, and Challenger • Hot Rods

The Bosch Hydro-Max®:
The Bosch Hydro-Max® is what we use for Ford, GM, Chrylser, International, and other Medium Duty trucks, with Hydraulic brakes and master cylinders with bore sizes 1-3/4 to 2 inch. It comes on many buses and tow trucks, along with almost anything built on a 6500 and larger commercial chassis until air brakes come in. It works off the power steering pump like the Hydro-Boost®, but instead of having an accumulator for backup, it has an electric motor that will continue to provide stopping assistance as long as there is a battery charge. International, GM, and other medium duty truck manufacturers will often have Hydro-Max® part numbers they say are obsolete, but we are be able to offer them because we have originals in stock, or reproduce the small parts that make them fit one vehicle or another.
Popular Hydro-Max® Brake Booster, Master Cylinder, and Electric Motor applications are:
• Freightliner • Thomas Built Bus • GM Topkick, Kodiak, B7 • Delco-Hypower Conversion • GMC and Chevy 4500 5500 6500 and 7500 • Blue Bird Bus • Travco Motorhome • Military Deuce and a Half and Half Track • Road Grader

Electric-Hydraulic Power Master Cylinders:
Electric-Hydraulic master cylinders are similar to the Hydro-Boost® in that they use hydraulic pressure as a source of power to help push a master cylinder. They might also be called "Electric Brake Boosters", "Electric Master Cylinders", or a "Powermaster", with versions produced by a variety of different brands like ACDelco, Advics, Aisin, Teves (ATE), and TRW and use an electric motor along with other accessory parts to build up the hydraulic pressure instead of using the belt driven power steering pump source that the Hydro-Boost® does. With the master cylinder will also be an electric motor pump to build up the pressure, a brake pressure switch or computer box to turn the pump on and off, an accumulator reservoir to store the pressure, and they may even have the abs block along with the wheel speed and transmission speed sensor all connected into it. There have been a few versions of electric-hydraulic master cylinders over the last few decades, and their fates have been mostly the same - you can't get a complete set of parts after 10-15 years. All of these accessories that build the pressure wear, they are expensive to replace, and, like most technology, the systems are abandoned after a few years for the newest and latest thing. We offer what we can for these systems, and then build our own conversion kits for vehicles where parts are obsolete, expensive, and impossible to source.
Popular electric-hydraulic brake master cylinder applications include:
• Hummer H2, H3 • Toyota 4Runner, Tacoma, and Land Cruiser • Lexus LX470, GX 470 • Lincoln Mark VII, T-bird Supercoupe • Buick Electra, Le Sabre, Reatta, and Riviera • Cadillac Deville, El Dorado, Fleetwood, Seville • Oldsmobile 98, Delta 88, Toronado, • Pontiac 6000, Bonneville • Land Rover Range Rover Classic Wabco Electric ABS • Saab • Jaguar • Buick Grand National and Turbo Regal Powermaster
