Vibration of Accelerator & Brake Pedals In Compass

Hi Guys,

I have a 2007 Jeep Compass. I am the original owner and it has 48,500 miles on it. Within the last month, Ive had my rear pads and rotors replaced, had front suspension work done (replacing both lower control arms) and a front end alignment.

About 3 weeks after the brake job, my accelerator and brake pedals started vibrating. A week after that, I heard a loud sweaking noise whenever I applied the brake. I took it back to Belle Tire last week, which is where I had the brake job done. Turns out they put the wrong size rotors on. They replaced them, at no charge of course. It drove smooth for a few days. Then, earlier this week, the vibrating in the accelerator and brake pedals returned. The accelerator vibrates quite a bit at speeds 40 and under. Not so much above 50 but it's still there. The brake it also vibrating whenever I stop.

Any ideas of what could be going on? Do you think it's still the rotors or something else? I'm really frustrated because I've spent $1000 on all of this work within the last month and I can't seem to get the bloody thing back to running smoothly. My money is low and I'm hoping it's not something else that needs replacing that's going to end up costing me a small fortune. Is it typical to have these problems with a vehicle with less than 50,000 on it?

No, I don't think I've ever had a tire balance. No one has ever suggested it to me. I don't know much about cars. I always depend on the mechanics to tell me what I need. I will have this done and hopefully, that will stop the vibrations. Thanks for the heads up.

I'll have to come here more often to educate myself.

You can get bad rotors even if new, especially if they have been dropped during shipping or by the insatller. If the brakes are squealing badly when new it generally means warped rotors as the surface for the pads is uneven and causes rapid wear in some spots while no wear on others. This causes high spots on the pads so when they do touch the rotor it creates a squeal. I would have the shop replace them, pads and rotors. Vibrations in the brake pedal are generally warped rotors, or broken pads.

Have them check that the calliper pins were installed correctly. If they reversed the pins then it will cause some problems.

Also check for a bubble in the tire. I had one that had good days and bad days and the ride/noise would even change during a 15 mile trip. It was different than the standard 'thump, thump' of other bubbles that I had in the past, it sounded more like a possible wheel bearing problem. I turned out to be a small bubble on the inside edge that grew so if I was parked just right you couldn't see it.
