Hydro boost I got brakes!!!

[bronco 69]

I got brakes!!!! Well only once while I was driving around the yard. Any ideas???

 

[americanhorses]

did you get a good bleed?

 

[bronco 69]

Nope... I've turned the wheel lock to lock no less then 300 times!!! Everything is in correct places and tight, so frustrating!!! But the couple times they worked wow!!!

You do realize, you can't bleed the brakes by turning the steering wheel. What's the problem? No brakes or no power steering?

 

[broncojo]

His other post states no brakes, only one inch of pedal that is rock hard. Did you eliminate the stock proportioning valve like suggested?

 

[bronco 69]

Yes I did remove proportion valve, i realize you can't bleed brakes by turning the wheel!!!! I'm trying to get the air out of the hydro boost system.

remove the pressure line going in the steering box, put it in a bucket crank the motor till fluid comes out , re-install line, refill PS
repeat normal steering bleeding procedure.

A common mistake, I made it repeatedly until told not to, is to take the box all of the way to it's stops. Don't do that. Yeah take it all of the way, but don't pin it against the stops. When you pin it the pump cavitates and froths the fluid with air, exactly what you're trying remove from the fluid.
