When I am idling at stop sign, then the car does not move after releasing the break pedal, even unable to accelerate. It takes a minute or two and then is running normally. Yesderday when I came out from express way after applying the brake, I was unable to pick the acceleration. I put the car aside and after few minutes it become normal. This is happening may be once in 15 -30 days. I have already changed the spark plugs, fuel filter, air filter, oil filter and oil. Got changed the front brake pads and rotors But this problem was before the brake pads change.
I would appreciate if you could suggest may any thing.

Hi,

What you describe sounds like you have a brake caliper or brake caliper slid pin that is not releasing properly. What to do is this. When this happens, drive the vehicle until it releases and then stop. Walk around the vehicle to see if there is one specific wheel that is hotter than the others. If there is, chances are that is the wheel that is hanging up for you.

Once you identify where the problem is, then you need to remove the wheel and inspect the caliper, caliper slid pins, and make sure the brake pads move freely in the caliper mount. Oftentimes, rust builds up on the caliper mount (where the pads sit) and the pads become lodged or stuck.

Here is where I would suggest starting. Safely lift the vehicle at the side where excessive heat was noticed. Have a helper apply the brakes so you are unable to turn the suspected wheel. Have the helper release the brakes while you check if the wheel is released, and you can turn it. If it takes time to release, then we need to move on.

Next, remove the tire/wheel. Once that is done, remove the brake caliper and inspect the slid pins, and check of the brake pads move easily in the mount.

If you look at the pic below, I highlighted the slid pins. The caliper will need to be removed to inspect these. They should move easily in and out of the carrier.

Also, check to see if the brake pads move easily in the brake support plates which attach to the carrier.

Here is a link that explains how to replace a brake caliper. You can use this as a guide to remove and reinstall the caliper on your vehicle.
