The ABS light is on all the time, also the ABS unit is running all the time and the only way you turn the unit off is disconnecting the battery. Can you give me suggestions on how to resolve this problem. The truck has new brakes and speed sensor. Thank you for your advice.

| When I stepped on the brakes the truck started jumping and made a loud grinding sound for just a few seconds but did slow down, a few minutes later when I stopped it was fine. After being parked and not running for maybe 15 minutes I took off again and drove four blocks, this time it slowed fine but made a screaming sound then three blocks later when I stopped it was fine. Any suggestions? | |

I have a 1976 ford F150 4x4 with vacuum assist:Front brakes will not relieve pressure after braking. I have replaced calipers, master cylinder, and front lines. I'm stumped and would appreciate any help.

Hi. My 2005 F 150 with 22,000 miles had a constant squeel in the brakes. The dealer turned the rotors and the pads are about 80% of the new ones. The squeeling in the brakes has returned but not as bad as before. Any suggestions? Reb |

The ABS light on my '99 stays on all the time now. Before, it was just intermittent. My mechanic says that there is a bad sensor in the differential and there is absolutely no safety issue. Another guy told me that if the light is on, the ABS system is not working (obviously a safety issue). While I've only got about 60K miles on it, I've just had the rotors replaced, after haveing them turned twice. Anyone have any advice? Thanks.

| I have an 06 F150 with ~20K miles with no problems of any kind. On recent trip was on road for ~6 hrs. When taking exit ramp I MAY (can't remember for sure) have TAPPED (not more) brake pedal. Suddenly (1) warning buzzer went off and at the same time (2) ABS light illuminated and (3) TCS light illuminated. I was on exit ramp so checked for brakes - - normal braking. ABS and TCS lights remained illuminated (steady). Drove home shut down and unpacked. Restarted truck to park it - - ABS light on steady and TCS light OFF. Checked several days later ABS light on steady, TCS light OFF. Any suggestions? Speed sensor? | |

Replying to: bassman45 (Oct 18, 2007 10:50 am) The bad sensor call is likely correct. If so, you don't have ABS. You DO have normal braking (probably why the mechanic says "no safety issue") You have to decide how badly you want ABS. While I've only got about 60K miles on it, I've just had the rotors replaced, after haveing them turned twice. Not common for any truck I've heard of. Were the pads gone? That said, I don't know (1) driving habits (2) operating conditions or (3) what kind of loads you're carrying. Could be a combination of all. Non-negative Fact: Some people wear out brakes (and vehicles) faster than others. |

'92, F350, dually, 141,000. Has belt driven type assist. I know that a slight hiss when pressing brake is normal and has to do with something called a brake assist. Prior to my last brake job at the Ford dealer, the hiss was short in duration, and when depressing the brake pedal, the normal travel distance before braking was approximately 2". After last brake job at the dealer (master cyclinder, calipers, drums/discs resurface, and adjust rea brake regulators), the hiss sound was much longer in duration, and the pedal travel increased to 4 1/2" (i.e. nearly to the floor starting from 6"). Ford has maintained nothing wrong. Wrong - it has been downright scary to have to press the brake pedal that far. (They system has been bled numerous times with no change - even immediately after bleeding.) I have since replace the MC with a MC with a larger (bore?). The brake pedal travel is now 3" (getting closer to the way it was before). Does anyone know 1) what would cause a longer hissing sound, and 2) is this related to a longer brake pedal travel distance? Thanks guys. Female needs help !!
