I have a 1995 F350 dually, quad cab 2 whl. Drv. Diesel, auto trans. This unit has the stanard brake sys (not Hydro-Boost) Never really had good brakes but now have gotten worse.I tow moderately with this unit. Problem occurred couple weeks ago, the pedal has gotten extremely hard pedal. Having had similar problem on a GMC unit I was certain it was in the rubber lines but no such luck, then replaced the power booster unit still no help, wondering if it could be in the ABS sys. Or proportioning valve. Any help would be greatly appreciated. Also have one other thing going on with this truck, when driving on expressway use turn signal when changing lanes trans. Acts like it down shifts. Had different trans. Installed several months ago and still doing the same thing. HELP!
have the same problem?
