My truck has been making a thump sound and It sounds like it’s coming from the front. It only happens as soon as I go, I stop and I go and I hear it and I don’t hear it when I am driving. I only hear it when I go. When it thumps I feel it by the brake pedal.

Hello my name is Dave.

Honestly it sounds like you may have a serious safety issue, there are quite a few parts that can cause the symptoms you have described. The most likely cause would be in the suspension. Here is a link to our tutorial on checking the suspension:

I would caution you to do your best to find the problem as soon as possible before you have a serious part failure that could cause loss of control. If you perform the tests listed in our tutorial and don't find the problem please let us know and we will do our best to help you find the problem. I hope this helps you solve your problem and thank you for using 2CarPros!

I recently replaced front disc and rear drum brakes. The rotors replaced. After a 2000 mile trip 3-days later the brakes became an issue. I noticed a little grabbing toward the end of the 2000 miles (in 3-days). The issue morphed into a situation where I would try to move the truck after sitting overnight or even a few hours and the brakes would be tight upon start up, so much so that at times I thought I would have to call a tow truck. The phenomenon would ease up after a few minutes run time. I did take the truck back and the shop said they adjusted them, should be fine. Two additional trips and the brakes are still grabbing, more obvious at slow speeds and ridiculous for the first few miles. I am wondering if the ABS system is malfunctioning or the shop has screwed up. NOTE: original brakes never grabbed although front rotors were warped from mile one and were not too shaky. This is the first replacement from original. Suggestions? Should I take to a dealership or can any decent shop check the ABS system.

If there are no codes stored in the ABS module, we can rule out any HCU problems. More than likely the shop may not have used premium brake parts. In addiation to that, it may have been a sloppy brake job.

Take it to a different shop and get a second opinion.

It lasts for my first five stops and is very irritating And loud. I've changed my front brakes for OEM equivalent Brembos. That didn't fix it. I pulled my drums and cleaned and adjusted the screw out until it was dragging on the drum a little and it got slightly better. All surfaces were smooth and evenly wore. No signs metal had contacted metal anywhere. I'm baffled and nothing online about my exact problem.

Brembos can squeak they have different pad configurations that squeak less. Can I ask which ones you have? Can you please shoot a quick video with your phone so we can see what's going on? That would be great. You can upload it here with your response. Please let me know

Spray the pivots with Silicone Spray Lube. It goes on like water, then evaporates leaving a slippery film behind.

Chrysler also has a product called Spray White Lube that is REAL effective but it can be messy. It sprays on juicy so the liquid soaks into the joints and takes the grease with it, then the liquid evaporates leaving the grease behind.

Check to see if hte bushing in the pedal or connector is worn down. If not lubing it always helps.

Is the noise constant, rythmic, or road surface reaction related? How does speed effect it?

It's a constant noise, I hear it mostly when I am rolling slowly. The road surface does not effect it, it makes the noise wither I am on a smooth surface or bumpy.

Is the brake pedal suppose to make a grinding noise and push out causing the vehicle roll a little bit more before stopping. It is equipped with abs.

I had purchased the truck 2 weeks ago and noticed the fuse was missing for the abs so I purchased one and put it in. Then decided to run some errands. Thats when the abs kicked in to find out that is whats happening in the above question.

The brake pedal is actually making a grinding noise and pushing out with great force to keep the brakes from locking up and the truck keeps moving instead of stopping then it will stop making the noise and the force to come to a stop. Oh it will kick in after slowing down in the middle of braking.

Right I am thinking about pulling the fuse again but not sure if I should yet. Yes the abs light was on before putting the fuse in but it did not turn back on while it was operating, the tires maybe the same size I didn't really check and as far as inflated to the right psi not sure at this point but they were 2 weeks ago

Abs is activating for some reason. You need a shop with a scan tool to monitor these actions when it is happening.

I dont see how there could be a grinding noise from the brakes themselves since they dont do it with ABS off.

The ABS module valve motor is bad, replace it, also.

GM had A recall on the ABS sensors themselves they corrode and then cant read the speed correctly, usually acts up worse at lowers speeds. You could take the sensors out and clean them real good or replace with new ones that shouldn't corrode like the originals had. And yes when the abs is activated to stop tire lockup it will sound like the pedal is grinding, and the pedal will push back. GM has mode the abs quieter as the years have went.
