|When I built my Carryall, I used a Hydroboost Brake system, supplied by Hydratech. At that time, they were truly a market driven company, supplying a quality product at a reasonable price. Its sad to say, but I no longer feel that applies. In fact, its impossible to even talk with the company any longer, you must go thru dealers. In building my M37, I found that the dealers were not able to answer my questions, and the prices were out of sight.|
I set out to find the components to assemble my own hydroboost system, using traditional truck parts, off shelf, and available at any NAPA and GM/Chevy Dealer.
I was able to cut the price almost in 1/4 and still have exactly the same product.
The following hydroboost will work with Power Wagon FFPW's, WC and M37.
All parts are used on 1991 Chevy V3500 trucks;
Master Cylinder 1 & 5/16" bore NAPA 39435 $47.88
Hydroboost Unit NAPA 52-7307 $178.00
You will need to buy the push rod, 2 springs and a baffle from a GM/Chevy Dealer
Push Rod 377397
Total Cost for the GM/Chevy parts $49.00
Complete cost for a Hydroboost system using the above parts $274.88
You can have custom made hydraulic hoses made at NAPA
You will need to cut the hydroboost push rod shorter and cut new 3/8" threads. Fabricate
a mount for the hydroboost to fire wall. You can now screw the hydroboost push rod into Helitool Suspended Pedals
Bleeding the air can be tricky. FIll your power Steering pump reservoir almost to overflowing. With the front wheels jacked up off the ground, and engine not running, crank the steering wheel lock to lock a few times. Refill the Power Steering pump reservoir again to almost overflow. Then Start the engine and IMMEDIATELY shut her off. I mean IMMEDIATELY, as soon as the engine starts shut her down. Refill the power steering pump to almost overflow. Repeat, start engine, immediately shut her down. Refill reservoir. Continue doing this until the level in the reservoir does not go down.
Then start the engine and run the wheels to one side lock, shut down the engine and refill the reservoir.....this time to its normal level. Start the engine and rotate the steering wheel to the other side lock. Refill reservoir to its normal level. Then start the engine and run the wheels back and forth lock to lock, shut down and check the level, refill if needed to its normal level. Keep doing this until the level does not go down. Thats it, you have the air out of the system. After sitting overnight, check her one more time as microscopic air will come out of the system and the level may go down a little.
Enjoy your Hydroboost Brakes.
