    how bad is it to remove the brake dust shields!

    I am about to rip these Damn shield off, they somehow get bent and then my rotor hits then causing noise and vibration...I bend then back and they go right back a week later.

    I am sure these help reduce heat to suspension components but can't see these being that important, BBK don't have them so why can't we remove these? They are easy to remove so would like some opinions.

    your factory brake shields are designed to protect the inside of your rotors from salt, debris etc. If you plan on turning your car to a track monster by all means remove them for better cooling. (minimal). or get brake cooling ducts and attach them to your sheilds. The outside air from the ducts will help keep your brakes cool aslo

    good info, I don't dive in snow is rain so I am glad I took them off. Also got rid of a vibration I had.

    My 335i use to do the same thing! it drove me nuts and was embarrassing! They just bent themselves in against the rotor! I just bent them back to much they never touched again!

    Better cooling for rotors isn't a bad thing.

    But do they also protect other components (bushings etc) from heat?
    I replaced mine with the backing plates off an F30 as they have a scoop built into them.

    Yes they do.
    They shield the rubbers of the lower control arms from the heat of the brake rotors.
    That's why I modified mine to at least shield these rubbers, bu give the rotors the air they need.
    Works perfectly.

    Yes, part number 4.
    It's questionable whether they actually make any difference but I thought it couldn't hurt to install them while I had my brakes off.

    Can you make a picture of one with the wheel in place to check if the scoop actually does stick out from the wheel and actually scoops air?

    I don't think it actually sticks out that far, but I'll take a picture.

    Dust covers removal should not affect your braking performance......

    I have the same damn problem on my left rear... would be annoying as S___ especially @ slow speeds 0-15. But cured the problem of bending it... I always was thinking of ripping it off... one more noise and its gonna get hacked..

    Nugs, did you end up taking a photo of them? I'd love to see it.

    I'm thinking of having these installed while I do the rotors/pads/fluids/SS brake lines.

    To modify them, all you had to do was drill an extra hole, am I correct?

    Sorry mate, I didn't and I no longer have that car.
    I'm not sure they actually did anything but I guess they can't hurt.

    Usually Dust Shields are made from aluminum alloy designed to keep the harmful and unsightly brake dust from covering your cherished wheels. They safeguard disc brakes,Brake dust is harmful and may corrode the metal .

    Pretty sure the main purpose is to prevent road debris, large amounts of water, etc. from getting into the rotor/caliper region, since the actual wheel (spinning while driving) protects it from debris on the other the other side. Also I assume to protect the rubber bushings/ball joints behind it from heat.

    The wheel side of the brake disc is not covered by the dust shield, so the idea that the shield is there to keep the wheels clean doesn't make any sense.


    On a DD, I would not remove them - too much chance of a small rock, stick, debris, dirt, etc. getting up between the pad/rotor and screwing up your rotor, pads, or braking performance. If they're making noise, buy a new one. If the new one makes noise, the dust shield wasn't the issue in the first place.
