Car Vibrates When Slowing Down?!?

Recently i have noticed that my car shudders and vibrates when i slow down..i have changed the brake pads and discs, also had the anti roll bars replaced. Also had the rear shoes and drums fully cleaned, but STILL the problem persists it vibrates and shudders when the car slows down.. can anyone help!|||My car always does this when I'm in the wrong gear for slowing down and haven't got the clutch down!!|||THE REAL ANSWER. First of what car do you have some cars are more prone to this problem then others. There is a combination of problems that are happening not just one. First of the rotors are warping from over heating and this can happen in as little as a 10 min drive at 60mph. Now the why because your brake pads are not moving back off the rotors when you release the brake pedal. This happens because the guide pin's or the Lock pin's (depends which manufacture your talking about) aren't moving freely like there supposed to on the caliper. Taking them of cleaning them and greasing them is how you fix that. the rotor should be replaced for a little better ones that can take a little more heat. I have used ATE premium one slotted and have had good results combined with a good ceramic pads. And a good bleeding of the system is also in order. This small changes are the key to preventing your rotor from warping. If you need more info please e-mail me, about the brakes or the bleeding part but I would like to know what car your talking about.|||There's a good chance that this suggestion won't help a bit. On the other hand, I done mechanic work thirteen years and it's worked for me multiple times.





Sometimes the brake lines can get a tiny tiny piece of trash in them and cause a restriction of good flow. This in turn will cause the calipers or wheel cylinders to pulsate. Do a thorough bleeding of the entire system.





If this doesn't help, take your rear drums off and put the rear of the car up on jack stands. Now, have someone push and hold the brakes while making sure the wheel cylinders are holding constant pressure. If they are not, you will see them expand and then slowly retract. If this is the case, replace them (always as a pair, don't replace just one) and do a thorough bleeding again.





Good luck to you. Brake problems can sometimes make even experienced mechanics pull their hair out.|||There might be two problems here......





The first problem is fuel exhaust intake. The worst thing that can happen is that there could be a leak in the gasoline in the fuel intake area and that can lead to a gunshot-like sound or "bang" called a "backfire"...the "bang" that you hear when you slow down your car.....in addition to the vibrating sound....I hope that "bang" is not happening to you. Deceleration backfires are common in this case. Backfires can mean serious problems so you better take it to an exhaust shop to fix it.





If you don't hear a backfire, looks like you are using the wrong gasoline and the problem is called "knocking". This is not the "banging" sound that you get from a backfire during deceleration. Be sure you are using the correct gasoline for your type of car and make.





Hope this helps.|||check your engine steady bars and mountings,if your using engine braking a loose or damaged steady bar can cause this problem. usually mounted on the engine bay bulkhead,sorry im presuming its a transverse engine.If its not and inline check engine mounts,gear box mounts also center propshaft bearing.Back to the brakes check caliper mounting and top and bottom ball joints/struts if fitted.|||That may be your bearings.... That'd be $$$$. Maybe tires need balancing or your front end is out of alignment. Those would be less expensive (maybe free). Go to where you purchased your tires. Les Schwab rotated mine for free and didn't charge for checking my alignment. They would've charged if they did have to align it though. Best of luck.|||It sounds like warped discs, this is especially true if the vibration occurs when braking. Try slowing without using the brakes and see what happens, no vibration then it is certainly the discs.|||Is it your brakes or your engine? Is it idling low? You can get the idle speed adjusted very easily at a garage if that's your problem.|||you replace the rotors? my first guess would have been warped rotors but if you replaced them along with all that other stuff i dont know where to begin really.|||When my car did this it was because the Tranny was grinding when I was moving into lower gears. I had a Auto but if you have a manual you might want to change your driving style|||Warped rotors or bad wheel bearings|||why dont you just be cheap and wait till it......... EXPLODES!|||Have your tires checked......when mine does that, it's always a tire problem. Good luck.|||does it feel like its going to stop because i got the same prob and im reckoning its the transmition|||ITS YOUR TIRES GET THEM CHECKED OUT . MAYBE JUST NEED TO BE BALANCED|||change down a gear!|||To high a gear|||check the motor mounts|||If they won't fix it,


L.E.M.O.N. Law!|||Are you not going in a to lower speed for the gear you are in?
