Hi Guys -
My car pulses when brakes applied and I feel the pulses on my break paddle a lot. Any thought how and whats causing this issue ?

 

Brake pedal. You've been *****-footing around. Find a lonely spot on a freeway and brake HARD down to about 10 mph, then return to speed limit. Lather, rinse, repeat. After six of those, you'll have scrubbed off the brake pad material that's transferred to the rotor.

If that doesn't fix the pulsing, have the rotors skimmed.

 

So what's causing this if its not warped rotors? What's wrong with the pedal?

 

Thanks slartibartfast -
Would this apply to drilled and slotted Rotors ?

 

Yes, you're just trying to remove the high/uneven pad deposits.

 

Poor braking technique causes this?
That is to ask,
can the deposits be caused by gentle braking?

 

Warping of rotors is very uncommon. Yes, brake pad material can preferentially deposit on the the rotor surface. That and local overheating creating cementite which is harder than the iron of the rotor.

Cementite. Ha, haven't heard that term since 3rd semester materials. That brings back memories. (Mostly hangovers)


Thanks for the link. Good read.

 

Ah, I learned some good stuff in there..
