Changing Audi A3 rear wheel bearing, brake discs, pads and caliper (8PA model code)

This 2009 Audi A3 (8PA model code) had noisy rear wheel bearings, so I decided to change them. I also changed the rear brake discs and pads at the same time as they were ready for doing. Just for good measure the caliper on the side I chose to video was stuck, so it got a new brake caliper too!
This car had covered 184,000 miles.
I started by jacking the car up and supporting it with axle / jack stands. After that I removed the road wheel and unbolted the brake caliper from its slider pins. This enabled the brake pads and brake disc to be removed.
The wheel bearing unit is held in place by a single bolt, which requires a M18 12 point / XZN / triple square bit. It's tight!
With the new wheel bearing unit and brake disc fitted, the time came to retract the brake caliper piston to accommodate the new brake pads. The piston was stuck so it was time for a new caliper. It is possible to refurbish the existing caliper but I didn't have time for that on this occasion.
I swapped the short brake line from the old to the new caliper and installed it on the car. Next it was time to bleed the air out of the new caliper and I used a pressure brake bleeder to help with this.
Finally the new brake pads could be installed, then it was time to put everything back together and take it for a test drive. Success!

Nice job and video ! I had to change the same caliper too ^^ And now wheel bearing on the other side but I ordered the wrong size on xzn thanks to AUTODOC how to 🙄

My current issue is whether I should follow AUTODOCS' instructions regarding an XZN #16 or the XZN #18 as he uses. Can you answer that?

The wheel bearing bolt torque is 180 N.m + 180° ? Pretty tight.

looked overtight to me whatever the manual said.

⁠@@duncan649I agree; I read online (auto doc) was 155NM, and Audi forum was 180-200Nm plus 180 degrees then somewhere else said just do it tight enough with a breaker bar making sure not to over tighten is so I thought sod it; I’ll just tighten it to 200nm that’ll be enough. After torquing I felt the nut with a breaker bar and it felt like if I went anymore something would go wrong so my gut instinct felt like 200nm was more than enough. Furthermore when losing the original nut (m18) it felt lose and didn’t take much to undo. Apologies for the long paragraph. This is my experience 😂

@@claireholdsworth5189 . Yeah. I recently changed the front bearings on my son's Audi, so naturally I didn't want the wheels to fall off! Used breaker bar to tighten 'enough' and they ain't fallen off yet!

I have a 2010 A3 TFSI and for the life of me I couldn't replace the rotor without having to take out the caliper bracket.

Would u believe I did this job on my neighbours A3 sportback today. Calipers, discs and pads. Took me 3 hours. When I looked at the job I broke my piston retraction tool trying to retard the piston !! So likewise recommended new calipers. You,re ment to bleed the caliper fully before touching the handbrake connection or reconnecting the cable. Everything went to plan today and I bled the whole system, got rid of old/ green brake fluid.
