I have a squealing noise coming from the back of my truck. I believe that it is somehow connected to the break system because when I step on the breaks is often increases or if it is not squealing at the moment it sometimes starts to squeal. It is not entirely consistent though; sometimes it won't change the sound much.
I jerked the breaks apart and the shoes look pretty good. They're about 5-7/32" thick. I noticed the break drum was fitting pretty tight so I loosened the tensioner at the bottom of the break.
After I did this I also noticed that the break fluid was a little low and so I added some. I haven't tested it yet as it is still up on the blocks.
Do you have any thoughts of what I should check into further to find out whatever is making the squealing sound?

Wow,your vehicle should have no brake noise regardlous of age,I have a 85 Nissan 720 truck,no brake noise.If they did the brake work,take it back again and if they don't fix it right,no noise and good brakes,let them know that you will go visit the BBB,You are required to take your vehicle back three times and if still not right,The BBB.will investigate.
Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.
You don't say what the year and model is - you may have an intake air temp sensor thats supposed to be in the intake manifold or the air hose that would be in the area of the back of the engine. If it is pulled out it would cause a hissing noise, not really a squeal. A squealing noise is usually a slipping belt or bad bearing.
yes...your engine belt is little bit lose that's y its causing noise...and hope when u speed up..it will stop squealing ..right?? so just tight your engine belt little bit and it will solve your problem in a min...take care n have a safe journey...n also if it help...rate it plz
The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.
