Can anyone answer me why the power brakes would also be lost when apparently I was loosing power steering fluid. Power steering fluid has sprayed all over the driver side tire and all underneath the frame. I also lost my brakes. Haven't looked for or found the leak but my guess is it is a power steering line that wore thru on the frame. I'll be getting up close and personel with it in the A.M.. Any suggestions? Thanks.

 

Worked on it today, answered my own question. The high pressure line from the power steering pum had blown its rubber "o" ring and fluid was flyin everywhere. The other end of this line goes directly to the valve for the power brakes. Apparently, the power steering pumps the fluid to this valve for the brake booster and so you will also loose braking ability! Cool!! I bought a new line from Advanced for 29.99, Ford wanted 86.74. Tough choice! All good now, no leaks. Probably will take some time to bleed all the air from the lines. Just gotta keep checking the level. Should be some pics attached, I hope!

 

It's called a hydroboost system...

 

Great post! The exact same problem happened to mine. Fixing it first thing in the morning!

 

To elaborate on his short post...

A hydroboost uses pressure from the powersteering pump to assist the brakes instead of vacuum.

 

Ahh and that makes sense now that I'm looking at the entire system.

Got it fixed, decided to post pictures of the new line for anyone else looking. Got it from Napa looks quality but only time will tell.

 

I think I have the same problem. Losing power steering fluid. I wondered why it affected the brakes. Now I know!

Is there a compelling reason to replace the whole line, rather than just the o-ring?

 

It's been a while since I did this repair but from I recall, the "o" ring is located on a fitting that is pressed on by the factory. There was no easy way to just do the "o"ring. New hose complete was just not very expensive, so I just di the whole assembly!

BTW, just wanted to be sure that Bartman569 was speaking about the "o"ring that is factory pressed on between the adjustment nut and the pressure nipple. Not reffering to the "crush washer" that is shown in the piture by kooper. That white looking "o"ring is actually called a "crush washer". Designed to craus and make a seal once you tighten down on the adjustment nut! My black "o"ring, shown in my picture on the original post, was the failure issure. Had to do a complete hose. I looked at Ford's hose assembly and also looked at Discount Auto. DA was considerable cheaper and probably made by the same company in Mexico as Kooper's. I only paid $26.99 for the complete line. Never had a problem since!

 

yeah you gota keep a eye on that stuff a friend of mine blew a line in traffic had to use the emergency brake to get home. i gotta check mine

 

brakes still work just gotta use ALOT more force my gearbox lost the seal on the bottom just havnt had time to do it but been drivin like that for MONTHS
