I need to know how to replace front break pads on a 1999 audi A6 2.8 quatto

I would say it's the temperature sensor on the rad that would cause this problem

Ask your neighbor for help

get the front breakes checked incase they need replacing if they are ok you can try cleaning the rust of around the disks also taking the pads out and putting a bit copper grease on the backs of the pads might stop them from sqeeking some time a harder pad will make the sqeek any way but try the above it should stop hope this helps ivan

who ever replaced brakes didnt grease friction spots on pads.

if it is like a vw then its the same

This is the brake pad warning symbol. You need to change either the front or rear pads, and replace the sensor.

first off, you need to buy the break pads, break caliper spreader, and you need to know if the bolts have a allen wrench head or a torques head, you can find that out by turning your wheel all the way to the left after you remove the front left tire, take a small hand mirror and look on the back side of the calliper, once you know what it is, you need the socket or wrench that fits it, remove the bolts, then the calliper will pull off by wiggleing it off, then remove the outside pad, take the break calliper spreader and place it the way the break pad sat and screw it pushing the calliper cylinder back as far as possible, then take the calliper spreader off and remove the other pad, install the new pads into the break calliper and replace the calliper back onto the router, (the round disc the calliper was on) line up the holes on the calliper and replace the bolts.......once you have put the calliper back on you must pump the peddle untill they are hard again, about 3-6 times or untill you cant go to the floor anymore. once they are solid again, replace your tire and you should be good to go.....................hope this helps.

Pads worn down to the break wear pad which sings or vibrates when pads need replacement.
Get new pads, ceramic and if you get the BEST ones, the will replace them FREE, forever ;-)
($100.00 at Midas, Brakes+ or the like and takes 20min)

sometimes if they get a glaze effect they will glaze up causing squeaks. Are they very shiny? if so they are glazed. Also are they factory pads or aftermarket do you know? Metallic pads almost always will give off a little squeak. If you know how to take off wheel and caliper you can remove the rotors and bring them into parts store and they can turn them real quick for you for about 20-30 for both of them. Just do the fronts. if you say your pads are fine leave them alone and just reuse them. This will help renew the brakes alittle but when you do replace pads in future always replace rotors as well dont turn them with new pads. and if you can, go with ceramic pads. less likely to squeal but just for a few hundred miles untill break in is over.

You will need to bleed all four corners, starting at the right rear, then left rear, then right front, then left front. Your bleed procedure always goes from the wheel farthest from the master cylinder, to the closest. By bleeding only the rear brakes, you've gotten air out back there, but not necessarily any air that might have moved farther forward. Bleed your rears again, and then move forward to bleed the fronts, and see if that helps.
