Front Brake Replacement - dust shields?

Changing the front brakes on my sons e53. Replacing the rotors, pads and sensors.



The drivers side front had almost nothing left of the dust shield. I have a replacement from FCP but the opening isn't large enough for the wheel bearing.



I'm really not into going deeper into the wheel bearing to replace the dust shield. Is there a funky way to get this over the wheel bearing or do I cut a slot and bend it over to replace?

You can cut the thinnest part to get around the bearing (from experience).

I usually remove when doing the bearing job and one time put the new bearing on before realizing dust shield still on the floor.

Thanks. That's what I figured. The passenger side is in much better shape. I'm taking that aside to see if it was cut now.

Can I ask about this ?

I just took the front drivers side knuckle off. I am going to get the bearing and hub pressed in.

How does the new brake shield go on without cutting it?

It won’t fit around the “shroud” that goes around the hub

What am I missing ?

Maybe I figured it out. The “shroud” I am referring to that surrounds the hub when installed is part # 31206751740 Dust Protection Collar, and according to RealOEM, it looks like it is a press fit onto the knuckle.. maybe I can tap it off from behind with a cold chisel...

The front dust shields have 3ea 10mm bolts the back side of the rotor and knuckle and you have to have the hub off to remove. Make sure the bolts are tight and use a drop of loctite (temp) as they can come out and the bolt will stay against the disc causing a godawful racket and possible damage (ask me how I know )

The dust collar is press fit. Once you have the hub off you can as you are thinking, tap it off with hammer and chisel. I usually replace them when servicing the bearing so I just hit it with a hammer no chisel needed. If I used a slide hammer to remove the hub I don't remove the dust collar. After putting hub back on, I will fine tune the shape of the collar to make sure it's not scraping the hub using chisel and hammer.

Your dust shields don't have 3 bolts keeping them from flexing and removing? Only press fit?

Mine have the bolts and the elongated C shape opening. Once the bolts are out it's almost free to remove except for the fact that it won't slide over the hub. After market or some Middle East mod?

We're talking about two different shields

The larger brake shield with the 3 bolts is what you are talking about.

I was referring to the smaller dust collar (press fit) that goes around the hub.

The part number above clarifies the dust "collar" that goes around the hub. I have made the goof of reinstalling hub before the brake dust shield and had to cut a slot at the bottom to install around the hub.
