Description: CLICK HERE FOR HYDROBOOST HOSES + FITTINGS Gearhead Online's all new 1964-72 GM A-Body Hydro Boost power brake booster kit generates 1200 to 2000psi to the calipers and is fitted with a Polished Wilwood master cylinder.This master cylinder features:Tandem OutletAluminum1-1/8" Bore SizePolished Wilwood's tandem chamber master cylinders are fully machined from a High-pressure die casting of a premium alloy, it incorporates slotted mounting flange to accommodate mount centers between 3.22" to 3.40" and also features side-hole mounts on 6.40" centers. Master cylinder has full separation between the front and rear chambers. Dual outlets allow for right or left hand plumbing based on mount location. Offers a total piston stroke of 1.10" and a 2:1 volume ratio between the primary and secondary chambers. This master cylinder comes with a 1-1/8" bore size and with a polished finish.The Hydro-Boost is powered by hydraulic pressure from the power steering pump. It requires 'no vacuum'. This has several advantages. No external vacuum pump required on low vacuum high performance motors. No 'small bore' master required. Firewall and valve cover clearance is increased. Frame mounted clearance is increased. Frame mounted Hydro-Boosts are the same width as a master cylinder, giving additional exhaust clearance. The Hydro-Boost can be fitted anywhere a vacuum booster will fit. It can use stainless braided hoses or rubber type and brackets are available for most applications. The Hydro-Boost uses fluid pressure from the existing power steering pump. The average power steering pump puts out from 800psi to 1400psi. The Hydro-Boost® uses this pressure that is always circulating through it, to convert to pressure to apply against the master cylinder. The output of the Hydro-Boost is affected by three factors. 1. The pedal ratio. We prefer that the pedal ratio be between 6:1 to 7:1. 2. The pressure output from the pump. 3. The master cylinder bore diameter. These are factors necessary to design the system that will work for a given application. It is imperative that the system be clean. Any residual metallic sediment laying in an old pump or steering box, will be floated up and through the system when the fluid comes through on start up. If any of this sediment lodges in the relief valve of the pump, there will be no pressure from the pump. This will result in hard steering and no power brakes. A filter or a new system is required to maintain the system in good running order. 260-8556P + 650 ZINC KIT + CLEVIS + HYDRO BOOST + HOSESKit includes: Hydro Power brake boosterWilwood Master cylinder (polished finish)1964-72 GM A-Body Firewall Mounting brackets4 Foot Hydraulic Brake Assist Rubber Hose KitThe Gearhead high quality hydraulic hose kit is just what you need to complete your Hydroboost or Hydrastop install.
