1.9 tdi rear brake disc removal

[S4_dan]

The Shed came with new rear discs. When I looked at them I have never seen discs like these before. They have a piece inside which to me looks like where the bearing is to be pressed into or onto.

Discs I've done in the past just usually have flat internal face that butts up to the hub.

Is there a certain way to change these discs? The car a 1997 model.
Tried googling and audi world tech but they appear to have the flush internal faces.

On a FWD models the the rear disc are a bit of a pain as the inner race of the bearing is pressed in either side. Another option is to put the disc in the oven and the bearing in the freezer and then they just about drop in (done that a few times before I got a press). You also need to press the ABS rotor on the disc or put the ABS rotor in the oven before fitting and again it just drops on... Also the bolts holding the caliper mount are a bit of a pain you need an 8mm allen key, and they are easy rounded.

Here is an exploded view of the setup..

Cheers for that. A job for the garage then me thinks!! Lol

This is what you're gonna be greeted by when you remove the disc,the bolt holding the carrier will most certainly round out and they are m8x1.25 thread can't tell you the depth of the top of my head,the rear bearing presses in the front just drops in and I held in place with a nut and split pin.

get stuck into it mate there not that hard

 

[S4_dan]

How do I get the old bearings out if there are pressed in?

Or is it a case of buying new ones?

 

[B5NUT]

Just buy new ones, cost is about £30 for the pair.

 

[S4_dan]

Just looked on eurocarparts. There are two sizes listed. I'm looking at the FAG branded bearings here: http://www.eurocarparts.com/mobile/wheel-bearing-and-wheel-hub

Anyone know which kit I need? Or is it a case of lucky dip? Lol

 

[aragorn]

Not sure why they list two kits, theres only one size of bearing AFAIK.

 

[S4_dan]

If you look at the specifications, the bearings have slightly different sizes. Really confusing. lol

 

[aragorn]

Yeh, audi themselves only list one bearing for the whole range of A4's as well as many older cars.

 

[B5NUT]

euro always list 2 bearing, the expensive & cheap one. I'm just replacing my rear discs & pads at the moment and I've purchased the FAG ones @ £18.48 each

 

[aragorn]

yeh, but theres another FAG one listed for 16quid which is what hes talking about!

 

[B5NUT]

Strange I only see one Part No.: 628440500

Correct.

Correct.

Why is it always difficult to order through these guys. Lol.

Out in the sticks it's easier to order off ECP and have it delivered for less than a pint of lager. If I went to local York Audi, it'd cost me about 2, maybe 3 pints of lager worth in fuel, plus an actual pint of Lager in the pub as I pass it on the way home!

What year car and model do you have?

 

[aragorn]

speak to Jason at All German, he'll sort you out with the right bits.

 

[B5NUT]

What year car and model do you have?

Checked with both my A4 1996 1.8 & A4 2000 1.9 TDI. Both give the same part number.

 

[aragorn]

Bingo:

FAG suggest its a chassis number break on very late 2000/2001 model cars, but oddly enough, Audis catalog doesnt mention it.

 

[aragorn]

Oddly enough, if you look at the cross linked part numbers, the part FAG have listed as fitting the late model A4's according to Audi fits all B5's. The part FAG list for early A4's is linked on Audis system to the older Audi 100/80 models.

 

[S4_dan]

So in turn, that should make the FAG Part No.: 628440500 on ECP the correct one, like B5NUT has ordered?

Just cross referenced the sizes from your links to those on ECP. The above ECP part number appears to be the correct one.

Why would ECP list the smaller, older bearing I wonder for my reg but not B5NUT's? Hmmmm

Many thank Kev, yet again, amazing help.

 

[aragorn]

I have no idea, becuase ECP's part numbers are meaningless.

 

[S4_dan]

I cross referenced the sizes listed on both sites.

 

[aragorn]

ah! yeh sounds good then, go for the "later" A4 bearings and you should be ok
