Warped rotors are the most likely cause, use a dial indicator to verify this.

One more problem. My Nissan Fuga vibrates when I step on the brake pedal at high speed. Does this mean I have worn out brake pads/disks?


not necessarily
if you have abs brakes it is the pulsations as the wheels lock and unlock from the abs activity
this transmits as a pulsation under your foot
it may also mean that the discs have warped and the warp is pushing the piston back in then letting the piston out
it is more noticeable at low speed light pressure stops but it depends on the speed
Take the vehicle to an accredited brake shop specialist and get a proper diagnosis done

What is causing noise in front? It seems to be a pulsing shudder as you drive. does not appear to be brakes related. any thoughts? Drive train?


It maybe your idler arms. When was the last time you had a wheel alignment? I would take it in for an alignment diagnosis. Describe what you stated and have idler arms checked.

2004 Ford F150 4.6L rear wheel drive. ABS pulsates at low speeds.


This may be an old school question, do you feel pulsating on the brake pedal? Have the brakes, themselves, been checked?

2005 Chevy impala brake pedal pulsation with brand new rotors installed


Is your ABS working properly? Under heavy braking the ABS should engage and 'pulse' the brakes on/off. It is normal to feel the brake petal flutter or pulse under your foot.

Under light braking there should be no pulsing as the ABS does not engage and you have changed the rotors and pads.

Hey I have a 98 volvo v90 wagon. I replaced rotors pads calipers and hoses from brake lines to calipers on the front. Now my abs light is on and when I brake only sometimes I can feel the brakes pulsating....


Hey man The ABS light is most likely a speed sensor out of range. It will not effect normal braking function. You have already spent a ton of money. Chasing an ABS light fault is not cost effective and you wont feel the difference. ABS problems are a dealer only option(expensive). Take that ABS bulb out of the dash and forget about it.

Changed rotors and pads on volvo s80 2001 but strong pulsating continues when braking


Abs control valve it's a big unit under hood with all the brake lines going to it then out of it to calipers. It has wire harness connector un plug it and try brakes aware that abs won't work but brakes will operate be careful until this is verified if pulsing stops that control valve has a problem. My advice is to never buy another Volvo I won't I had one

ABS pulsing at low speed


Sounds like your brake rotors are warped.Take them to a machine shop and have them refinished or trued up.

When braking on my '04 Suburban, it pulsates like it has a warped brake rotor, but rotors are true (all four), and there is no correlating pulsation in the brake pedal, nor in the steering. Also, this...


Try pulling the fuse for the anti-lock braking system. If the problem goes away with the ABS disabled, check the wheel rotation sensors for problems, especially cracked or broken mounts or wiring issues. I'm thinking a sensor is dropping out when it gets heated by the brake and feeding bad data to the controller. The controller than treats it as a low traction situation and starts pulsing the brakes. If this is the case, you would see an ABS or Low Traction warning light on your dash.

Another possibility is a worn or loose suspension component oscillating under braking stress. In particular, check the shock absorber mounts. You could also have a pad that chatters instead of gripping the rotor cleanly - this may leave marks on the rotor, and would probably produce an audible noise.

2003 Nissan Sentra automatic When hard braking at highway speed, get pulsing vibration - tires/alignment/shocks or sturts


Probably your ABS brakes. Thats how they work, they pulsate so as not to lock up and go into a skid

Pulsating gas pedal in low speeds, if you go really easy on the pedal untill ~25, it will not pulse at all.


Make sure the carb is bolted tight to the manifold too. Loose nuts can cause this.
