Here's the history: I have a 99 f150 5.4 4x4 with 285x75x16 tires. My baby started squealing when I would stop and continue to squeal when I started to move again. I took her to the Ford shop and they said my front rotor's needed replaced and my back rotors were going to be machined. They also replaced all the brake pads . This was supposed ly the cause of the squealin'. Two days later the squealing came back, took her back to the shop and then told me that my back brack pads needed performance pads, a 30 dollar difference. They told me that this would stop the squealin'. Now, one month later the squealin is coming back. It's not that annoying yet, but it's startin to increase as time progresses.

Everytime I start to move after I stop I hear the squeal and you can hear it move with the tires. It also happens when I make a slow turns. I believe the squealin' is coming from the rear, but I can't be sure.

The questions I have are:
1. Would aftermarket rotors and brake pads solve this annoying problem
2. Could the cause be the self-adjusters
3. Should I be concerned in terms of safety.

Any advise would be greatly appreciated. This is definitely not the way I want peoples head to turn

 

Yeah, brings back memories. My neighbor with the same truck package had a squeal in the front and a deep hum from the rear brakes. The deep hum is common on the rear driver's side. The 4x4 rear rotor is a combo rotor / drum. The parking brake is the drum portion and the rotor is for momentum.

Using Semi-Metallic pads are a no-no. Spring for the performance friction carbon metallic. Doing that and replacing the rotor cured the rear. Using the carbon metallic cured the front noise. All were bought at the local Autozone. If you have trouble stopping, then it's a safety issue. Otherwise, it's more of an annoyance.

When you pull the rear rotor, take a look at the parking brake/drum pads to see if they have signs of scorching. You may also have a binding problem. Good Luck

 

Thanks for the detailed info. I plan to do that and hopefully this will solve the problem. Thanks for the time

 

I thought I was the only one having these problems. I had that noise just before my pads wore out. I figured it was the brakes, so I took it in for a brake job. Two months later, the noise was back. Took it back to the shop and they re-turned my rotors and soaked the pads in some type of solution. Two months later, noise again. Figured I'd to the job myself with quality pads and I even replaced the rotors. The noise was still there. It is coming from my right front wheel. Funny thing is, when it rains, the noise goes away. I figured something down there needed to be lubed. I'm going to repack or replace the bearing and completly inspect the CV boots. Hope something works.

Oh, I have a 1999 Ford F-150 4x4. 5.4 liter with off road package. I'll let you know what happens.
