HI I HAVE A 99 AUDI A-4Q THE PROBLEM IM HAVING IS WHEN I TURN TO THE RIGHTONLY AND STEP ON THE BRAKE PEDAL IT FEELS LIKE SOMETHING IS MOVING UP AND DOWN AND SOMETIMES IT DOES THIS GOING STRAIGHT AND STOPPING AT A SIGNALLIGHT AND BRAKE. WHAT SHOULD I LOOK FOR? THANKS MAX

 

Max, first turn your Caps Key off... all capital letters looks like shouting, and you might not get many responses.
Pull the wheels off, check the brakes, you may have something loose... brake pads/ calipers.

 

do you get an abs light when this happens? if your car has a vacuum brake boost it might be going bad or have a lose connection

 

HI I dontget aabs light on when this happens but i will take a look at the brake boost is thereanything else i should look for?THANKS

 

Biggest thing is what Wolf was saying - take off the wheels and check everything carefully - make sure all the required bolts are there and are torqued correctly, and make sure the pads are seated correctly. Also, when you reassemble, be absolutely sure you use a torque wrench to set your lug torque to 90 ft-lbs, and torque in the "skip-one" star pattern.
