Brakes

I have a 97 F-350 four door 4x4 7.3 automatic. I was driving today and hit the brakes and they were hard as a rock. I called my mechanic and he said pull the hose off of the front of the brake booster and see if the vacuum pump is working. So I did it but it didn't seem to be pulling very hard on my finger but he said it was fine so I replaced the brake booster and it didn't fix it still hard as a rock. To me the vacuum pump is even weaker so I am going to replace it tomorrow...any ideas on something I should check first or is that the natural progression?

thanks

I question the front hoses to the calibers. They may have junk in them that blocks the passage ways (that's why the pedal is firm). If you try and bleed the front brakes, they should provide a solid stream. If not, the line is blocked.

Wrong Forum. For a 1997 F-350, you want to be here:

1987 - 1996 F150 & Larger F-Series Trucks (296 Viewing)
1987 - 1996 Ford F-150, F-250, F-350 and larger pickups - including the 1997 heavy-duty F250/F350+ trucks

Will get more responses over there!
