Transmission problem i have a nissan STA exalta 2001, the transmission i think hummmms like a stuck brake pad. i checked the rotor disk of the break but it is not hot after a long drive. the Automatic transmission i think does not shift regularly. what do you think is the problem and how can i solve it

Your engine or transmission supports maybe worn out. Check and replace them please to avoid jolting.

• Well when you looked at the brake pads after your drive were the pads stuck to the rotor?
• First thing to do is double check your pad and rotor installation.
• Also check to make sure the right parts were installed.
• When you pushed back the pistons on your calipers did they flow back nice and smooth? Did they wedge in and get stuck? This would make the pads drag.
• If you used grease did you get some on the pad by accident? If this is the case it will burn off.

• How is the car stopping for you? Properly? Do you hear any grinding while driving slow? While driving fast? Over heating rotors will turn a bluish stain. That is when it is really time to be worried.
• If your brakes are not dragging then give some time for the pads to ware in.
• If the piston is stuck forcing the pads against the rotor all the time then you need to replace the calipers.
• Don't forget to bleed the lines afterword.

It's good to have the rotors turned when you replace your brake pads. It should not cost too much. And it keeps the new pads from wearing down so fast.

check the level of the power steering fluid.

I don't think you should be having trouble like this not this soon how ever it sounds like you have a stuck brake caliper .check the rotors and see if you have any groves in it. hope this helps you!

Make sure the rotors (the disks that the tire rim are mounted on), are smooth. If they are rough, then they are wearing your break pads down. Even if the break pads are new, bad rotors will grind them down. Change the rotors...

i think you mean the rear calipers, this is the part where the brake pads are squeezed together

Check the brake system such as the break paqds, calipers or rotor. Check that nothing is loose. Also check that the steering is well lubed.

Sounds like a warped break rotor. Needs breaks.

You will need a jack and 2 jack stands to get the front wheels off the ground (break the lug nuts loose before lifting) and support the vehicle.

You will need the lug nut wrench (or a 1/2 inch breaker bar and 21 MM socket) to remove the wheel.

You will need a 14 MM wrench to remove the caliper bolts and possibly a flat head screwdriver to pry the caliper off of the pads if it is difficult.

You will need a big pair of channel lock pliers to compress the piston back into the caliper bore to allow room for the new pads.

You may need a hammer to hit the rotors to break them loose if they are rusted into place on the hub- a couple good shots should break them free if needed.

You will also need a wire brush and some good brake grease (available at any parts store). You will want to see any place that the pads contact a stationary surface and clean this area and apply a film of the grease to these points to prevent binding and uneven pad wear.

Hope this is helpful!!
