Brake booster conversion

Post by sm350bl »

Has anybody converted their coach's from vacuum assisted brake boosters to the hydraulic assisted ( hydro-boost ) setup? If so, was it worth it? Wondering if there enough advantages to make a conversion worth while.

Just to add some info, hydro-boost uses hydraulic fluid from the power steering pump to give assist to the brakes. At my work we have a mixed fleet of e350 and e450s. All of the e450s have hydro-boost. According to some posts from the sportsmobile guys the hydro-boost conversion increases braking force by around 30%. I find this appealing since mine has the diesel and relies on a vacuum pump. I do have bigger front brakes than the stock 2wd e350 since I have a F350 4x4 dana 60 front axle and I am thinking anything I can add in the brake dept is always a good thing. I know I have a couple hydro-boost core units upstairs at my work. I think retro-fitting wouldn't be that heinous either.

How much more braking force are there between the front end off a newer E350/E450 donator, compare to the older stock E350? I saw a few of us beef up the front end that way.

It sounds like you already did the front end upgrade, and now looking into the booster as additional braking force multiplier?

Sounds like a great idea, and it sounds like you would be the resident expert. Let us know how it turns out.

The econoline got its brakes re-vamped in 08' in the body change over. They are much larger components and a great upgrade. My stock front end was pulled from under the rv when Salem-Kroger did the 4x4 conversion prior to delivery. They used a 2001 F350 dana 60 front axle that does have wider rotors. I am not sure about overall surface area between the stock 2wd e350 rotors and the f350 rotors.
I have noticed while starting to put some miles on my chinook that a fair amount of foot force is needed to tame the beast. Not horrible, but noticeable. The vacuum brake booster just taps into the 15 inches of vacuum supplied by the belt driven vacuum pump, the hydro-boost gets to take advantage of the power steering's pumps thousand some odd psi of pressure to exert force with. I am thinking that I could be able to piece everything together fairly easily since its all ford stuff from the same years/vans. Other google searches have yielded a fair amount of these conversions take place with favorable results. I am just in the pondering stage but I think im curious enough to see what I currently have in spare parts and come up with a list of other parts needed, brackets, lines ect.
