Changed pads and turned rotors not to long ago. Everything was fine for a few thousand miles. Now I have an intermittent pulsation when braking. I rechecked everything, and did find the outer pad on the passenger side lost its lower tension spring. Could that be it?

Question...

Whom turned these rotors?
Why when new ones are so cheap?
Were they checked for lateral run-out after turning?
What was the reading?
What was the final thickness after turning?
Were the lug nuts properly retorqued to the
proper specs in the proper order or just run
up tight one by one with an impact gun of
unknown quality?
This can also cause pulsating brakes even with
new OEM rotors.

Missing clips will not cause pulsating.
Warped or mis-turned rotors will...

Turning rotors is a fine art and not everyone can do it properly.

Did I mention everything was fine for a few thousand miles??

Your responses in both of your threads make you sound like a total ***...

Agreed.

I think 157dB's questions are on point. My money is on warped rotors.

While a warped rotor is one possible cause of brake judder there are others. Uneven pad deposits on the rotor for example. This is very common when brakes are used hard and heated beyond their rated capacity. Pad material builds up on the surface of the rotor and when they get too hot it sort of smears and can build up differing depths on the rotor face sending a pulsating feel thru the brake pedal. Looking at your rotors you might be able to see this if its occuring - it looks like round spots on the rotor here and there. If the rotor is totall shiny then this is probably not the issue.

There are several options to deal with this:
- Guys who track their cars usually have track specific pads that are more abrasive when not up to temp. Throwing those on the car and doing some normal street driving will scrape off the old pad material. But, if you don't have a set than this is of no use.
- Pull the rotors off and sand them to remove pad build up.
- Try doing a bedding process - do a few hard brakes from 40, then 60 then 80 mph. Get up to speed and firmly brake until about 10 mph, repeat. Let sit to cool when done. This can sometimes scrape off the high spots.
- New or turned rotors.

Lets say you have some pads and rotors that are newer (couple thousand miles), can you safely just resurface the rotors, with new pads ?
