Message: [QUOTE="Peroni, post: 65280, member: 315"] I never did like the feel of the vacuum boosted brake system. After adding custom rear disc brakes I thought a hydroboost conversion would compliment my upgraded braking system. I used parts for a 97 F Superduty and they are a 100% bolt in deal. Here is my parts pile. Everything is brand new except for the PS Pump with is a new reman. I also added a better ps cooler too. [ATTACH=full]65443[/ATTACH] The old vacuum booster and master cylinder removed. There is lots more room now! I blocked off the old booster vacuum line with a plug. [ATTACH=full]65444[/ATTACH] The new booster is a direct bolt in. Be wary in getting a reman unit as not all of them come with the pedal rod or mounting plate! This one is a brand new Motorcraft part. [ATTACH=full]65445[/ATTACH] New 1 5/16 master on the left, original 1 1/4 master on the right. [ATTACH=full]65446[/ATTACH] The new master came with a revised harness adapter for the cruise control sensor. It's a direct plug in as is the fluid level sensor. [ATTACH=full]65447[/ATTACH] Both brake lines are a direct fit too, no adapters required. The big silver sensor if for my BrakeSmart controller. [ATTACH=full]65448[/ATTACH] New power steering pump. It is the same as the stock one except the reservoir has an extra barb for the second return line. You can also tee into the power return line and keep the stock pump. [ATTACH=full]65449[/ATTACH] Pressure in/out and return lines installed. [ATTACH=full]65450[/ATTACH] I used a Derale frame mount trans cooler for the PS cooler. It mounts with two 1/4-20 bolts and fits on the cross member nicely. To protect it from road debris I used heavy course mesh stainless screen and secured it tightly with wire on the backside. [ATTACH=full]65451[/ATTACH] A Magnafine filter was installed in the return line. In case the pump or steering box ever failed I didn't want the fine passages in the booster getting clogged. It is secured with a 2" standoff pipe clamp. [ATTACH=full]65452[/ATTACH] This project took me about 5hrs. It was awful hot and humid so I had to work slow and take some breaks along the way. Refilled the steering system with Schaeffers transmission fluid, master was topped off with blue ATE brake fluid. My impressions during the test drive were excellent, pedal feel is firm and consistent with less pressure being required to stop the truck than before. As a test I backed my 25" gooseneck trailer down our steep driveway. I had no problems operating both the brakes and steering at the same time. This was a very easy mod that requires no special tools or any modifications to the parts and the results are a truck that actually stops when I want it! :thumbsup: [/QUOTE]
