What causes brakes to shake right after rotor and pad?
The shimmy feeling that comes from brakes is usually due to uneven friction material build-up on the rotor. This transfer from pad to rotor is supposed to happen, indeed it makes the brakes work better, which is why brakes function better after break-in. However when it happens unevenly, it produces a shaking or shimmy feeling.
Why does my car wobble when I hit the brakes?
If you hit the brakes and feel your car wobble or shudder, it’s time to give your brakes a thorough inspection. It’s likely a classic case of warped rotors. Braking removes material not just from the pads, but from the discs as well. As rotors get thinner, they are more susceptible to warping because of the heat generated during braking.
Why does my 1998 4Runner shake when braking?
Not sure what to check next 1998 4Runner, 242,000 miles. I have a 2000 4Runner with 200,000 miles on the clock. It has had front brake shudder from day one. The rotors have been turned (and replaced) many times, but within a short time the shudder returns.
Why do my brakes shimmy when I run through a puddle?
What is passed off as a “warped rotor”, and blamed on the user running through a puddle after heating the brakes, is a myth. The shimmy feeling that comes from brakes is usually due to uneven friction material build-up on the rotor.
Can a warped brake rotor cause a shudder?
In our experience this results in a great many problems. If the pad does not help to remove heat or if it generates too much heat the rotor will be affected. Small cracks in the face of a rotor, or a blue color to the metal are signs of too much heat. The symptom is a warped rotor and brake shudder. Sometimes aftermarket pads do not fit properly.
Why does my car shudder when I put the brakes on?
It feels a lot like a wheel shimmy, except that it starts when the brakes are applied and quits when they are released. The cause of brake shudder is warped brake rotors. When a brake rotor warps, the two faces no longer travel in a straight plane.
What causes a brake rotor to wobble and wobble?
The cause of brake shudder is warped brake rotors. When a brake rotor warps, the two faces no longer travel in a straight plane. Instead they wobble from side to side or run in non-parallel planes.

What causes a car to judder after a brake change?
Note the emphasis on the word even, as uneven pad deposits on the rotor face are the number one, and almost exclusive cause of brake judder or vibration. Improper bedding of your brakes after replacement can cause the issues you are talking about. To fix this, you’ll need to take your rotors back off and have them re-burnished.
What should I do if my brake pads keep juddering?
Again, a simple brush should suffice for removing all the excess debris, but if this has built up appreciably, it might be better treated by gentle rubbing with sandpaper. Brake pads generally have a lifespan of a couple of years according to the AA.

What to do if your brakes pulsate after rotor and pad?
Check all installs with a dial indicator for runout. Spin the rotor with indicator at 90 degrees on the rotor face near the outer edge. Runout should be zero, must be under .004″, the less the better. Clean pad back, piston, and caliper. Replace shims. Proper and complete lubrication of all metal-to-metal contact points.
Why are my rear brakes making a noise?
It’s not your new brakes, it’s your rear or something else like a hub, bearing or cv joint (I would think it was any of those three since they often make noise at all speeds). Also, remember that just because you just did your brakes, it does not 100% mean that this is a brake related issue.
When do I brake do the vibration go away?
Not when braking, just when driving. Starts around 40/45 gets worse through about 60/65, then starts to mellow out, although it doesn’t fully go away. No pulsation or vibration when braking. Since then, I have had the wheels balanced, replaced bad control arm bushings and still have the vibration.
What causes vibration when clamping on brake pads?
However, if pads are contaminated with oil, dirt, or other substance, then it causes vibration during the clamping of brake pads onto the rotor. Besides this, the wrapped, damaged, or excessively worn pads can also be one of the causes of brake pedal vibration.
What to do about vibration after changing rotors?
The new rotors are coated with an anti-rust material that must be completely removed, otherwise it will embed in and contaminate the brake pad surfaces. kurtwm1June 24, 2017, 11:20pm
What should I do if my brake rotors are bad?
How To Fix: Brake rotors need either resurfaced or replaced. Replacing or resurfacing both rotors (front set or rear set), even if only one of them is in bad condition, is crucial. New brake pads are highly recommended when replacing the rotors because worn surfaces of the pads will not make proper contact with new smooth rotors.
Why is there an extra hole in the rotor?
Many rotors have an extra hole machined in the rotor. It is usually located between two of the stud holes. I am not sure of why it is there, perhaps to help balance the rotor or to aid in the machining process. What can occur is that a small amount of rust will form on the hub flange.
When do CV axles need to be replaced?
Because the CV axles are the direct link that transfers the power of the engine to the wheels, they are subject to high levels of stress over time and will eventually wear out and require replacement for proper functionality to return. When they do wear out, the CV axles will usually show symptoms to let the driver know they require attention.
Which is the best cv shaft for Nissan Maxima?
An AutoZone drive shaft for Nissan Maxima protects your car with crack-resistant CV boots that keep dirt and moisture away from the joints. A Maxima axle from AutoZone extends the life of your vehicle’s CV joints with high-quality grease that stands up to extreme temperatures and high torque.

Can a cracked CV boot cause axle failure?
A torn or cracked CV boot will leak grease that ends up tossed around while the axle turns. A leaky boot will eventually lead to CV joint failure, as dirt and debris will get into the boot and damage the joint.
