The thing it might be on all wheels but its a metal piece not the rotor not the calipier and not the wheel or brake pads. Its circular and well the jack gave out (luckly i wasnt under the vehicle at the time) and it crushed a bit ago and i forgot all about it. (bought new jack stands and a new jack vs that old tall black original crap one)

so whats that peice called?

I know this isnt it, but any comments on this brake dust thing?

 

[vipercrazy]

its usually referred to as the dust shield but yes the tire covers are also called dust shields.

for drum brakes they use another term since the plate actually serves a purpose

it shouldnt have bent that much, they are rather strong

 

[240Dbio]

i didnt really get a good look if it was bent good or not when i did it with my nissian centra(front wheel) it bent real good. I assume it did the same with this Dust shield; ill have to look for it. I looks in performace products no luck; the search continues!

My car came with those items when I put new tires onI made sure they toss those away. why do you think your bluntzs and steel wheels have those openings for. Its to help keep your brakes cool these covers are just asking for brake fading and overheated brakes. That's just my thoughts I saw them on and didn't like the idea.

I would have to agree. I think the occasional cleaning of the wheels is a lot easier than replacing pads and rotors.

Wheel dust shields won't make a measurable difference in rotor cooling- more cooling is done by conduction through the wheels, axle, pad and caliper than by air on the rotor. Those are cooled by the surrounding air, and suffer no paucity of flow from having dust covers installed. The centrifugal flow of air pumped by the wheels -regardless of design- will more than overcome any "shrouding" the dust covers (which are vented) might provide. They'll help keep water off them in the rain, as well.
Sounds like the part your bent was the rear dust shield.
On drum brakes, it's called the brake backing plate, and it's what the shoes, and from there the rest of the car, are attached to. They're what transfer braking torque to the chassis.
On disc brakes, the dust shield keeps mud and crap off the rotor. The wheel is supposed to keep the outside clear.

And, it is never a good idea to jack a car up using the brake backing plate, front ot rear.

 

[240Dbio]

o no no; i jacked it in the whole, but the mercedes benz jack well lets just say its not very stable once the car is bumped.

If it didnt crack and break off from the impact you should be able to take a pair of pliers and bend it back to shape.

I keep the original jack in the trunk in case I need it in an emergency. A good hydraulic jack and stands are what you want for home.

Also, you always want to chock the wheels! (And use the emergency brake.)

That really should be obvious.

thanks for the tip i will do so once i replace my rotors and brakes next weekend

Those wheel chocks Greg is talking about above are at an $18 bid on e-bay. I bought mine directly from the dealer for about $5 a year ago. I can't believe what some people will pay for things on e-bay!!
