When letting off the brake pedal why would there be a knock or clunking noise?
Front brake shoes are sometimes attached to the calipers by "spring clips" and these can rust and break causing your pads to "float". Sometimes calipers get rusty or pitted on the hydraulic shaft and don't retrack smoothly when you let go of the brakes. This is more noticeable if the pads are well worn. The same happens with the rear shoes. If they are well worn, there is a lot of dust in the vicinity and it can foul your automatic adjusters so the shoes aren't close to the drums and you hear noises. If the noise can be localized to one wheel and the pads are OK, then you might need a new caliper.

It can mean that your brake shoes are "glazed" and this isn't really a problem. It can also mean that excessive brake dust is making the noise and this isn't really a problem. It can mean that your brake shoes are worn and now metal-on-metal contact is beginning to happen and you should get a brake job immediately before you destroy your brake rotors. It can also mean the brake pads may have built in…

What causes a Saturn SL1 to continue to make clicking and clunking noises when you turn and when you brake after the CV axles have been replaced?
Check the strut assembly on the side that is making the noise. It is possible that the strut is starting to go and that's what is making the noise. This may especially be true if you can make the clunking sound happen by pulsing the brakes as the car is moving forward. I just went through a similar problem with a 1997 SL2. The car had only 78,000 original miles when I had new brake…
