Audi A4 Quattro: Have a 2005 A4 B6 3.0 Want to replace my rear

This answer was rated:

Have a 2005 A4 B6 3.0 Want to replace my rear brake pads. I'd like to do the job myself, but don't know what's involved. Is this a simple job, or do I need specialized tools, etc.?

Fidhle007 :

Hi there!

Fidhle007 :

My name is XXXXX XXXXX I'm a BMW tech, hopefully I can help you today!

Fidhle007 :

Rear brake pads on your Audi are very easy if you are patient and mechanically inclined!

Customer:

(&^)*&&)(*!

Customer:

When I asked my question and signed up there was an Audi tech queued up!

Customer:

What a ripoff!

Fidhle007 :

I work on audis as well

Customer:

Have you replaced rear pads on an 05 A4 B6 3.0?

Fidhle007 :

I just identify myself as a BMW tech because that is my specialty

Fidhle007 :

Many, many times

Customer:

RTFP

Fidhle007 :

RTFP?

Fidhle007 :

I'm sorry, I don't follow

Customer:

Have you read my question?

Fidhle007 :

I have, what do you mean by RTFP?

Fidhle007 :

You will need one special tool to do the job, a piston compressor

Fidhle007 :

It can be rented from any decent autoparts store

Fidhle007 :

one second, I'll find you a picture so you know what you're looking for

Customer:

Can't turn them and compress them that way?

Fidhle007 :

You have to compress them while turning them

Fidhle007 :

it can be done with a series of pliers but it's a pain that way

Fidhle007 :

if you're adventurous you can try but I'd recommend borrowing/renting the tool

Customer:

OK, thanks

Fidhle007 :

Other than that, remove the top caliper slide bolt (it's usually a 13mm)

Fidhle007 :

and pivot the caliper back and down

Fidhle007 :

You should be able to easily remove the pads now

Fidhle007 :

using your special tool

Fidhle007 :

compress the piston back into the caliper

Customer:

I was fearful that it might involve a more complex procedure. Does the fluid reservoir back up when compressing the caliper piston?

Customer:

i.e. overflow?

Fidhle007 :

Apply a small dab of anti-squeal compound to the backs of the new pads and the very edges where the pads ride in the pad carrier

Fidhle007 :

be careful not to get any on the discs or friction surface of the pads though!

Fidhle007 :

The reservoir should not overflow

Fidhle007 :

the volume of the rear pistons is very small

Fidhle007 :

But to be safe, check the fluid level before you start. If it is full up to the top, suck a small amount out using something along the lines of a syringe or turkey baster

Fidhle007 :

just don't reuse it for food afterwards though!

Customer:

Sounds good. Do you know if there's a diagram from the manual online where I can look at it?

Fidhle007 :

I can post a link to a video if that helps!

Customer:

Sounds great! Thanks

Customer:

Thanks for the pic! Is the 2001 A4 the same as my 05 B6? Thought the B6 wasn't around until'03...

Fidhle007 :

It's very similar, Audi has used the same basic system since the 90s

Fidhle007 :

VWs use a similar system as well

Fidhle007 :

Really, the only variation between the versions is whether the E-Brake cable comes in from the top or the bottom

Customer:

My first car was a '69 VW ragtop!

Fidhle007 :

Yours should come up from the botXXXXX XXXXXke the '04 in the video I linked

Fidhle007 :

Fantastic, I love those cars!

Fidhle007 :

Basic rule of thumb is to remove the caliper slide bolt on the opposite side from where the e-brake cable comes from

Fidhle007 :

that way you can actually pivot the caliper out far enough to get the pads clear

Customer:

It was a great car -- wish I still had it. Completely restored it and sold it when I went into the Navy..

Fidhle007 :

You'll just have to keep your A4 for 25 more years!

Customer:

Don't laugh -- my S4 had 586K on it!

Fidhle007 :

Nice!

Fidhle007 :

I had 330k on my old BMW E30 when I finally decided to build another...

Customer:

Fidhle007 :

It would have kept going except for the stupid New England rust!

Customer:

Why haven't you gotten an Audi?

Fidhle007 :

That's awesome, thanks for posting that!

Fidhle007 :

I'd like to, I just get a better price on BMW parts!

Fidhle007 :

I have several friends with audis though, they're really nice cars to drive when they're in good shape!

Fidhle007 :

I've know a few that weren't in good shape though...

Customer:

My S4 was a '93 and never had any rust until the very last winter (had a dent in one of the rear doors)

Fidhle007 :

They're fun cars to drive, I'm not surprised you put that many miles on!

Customer:

I would have kept her, but the doors were all seizing. Was afraid she'd lock me out one frigid night. Parts were getting hard to find and prices were too high. I like the B6. Good motor.

Fidhle007 :

I have a customer with the same car, it's really nice! Your's isn't silver by any chance, is it?

Customer:

Black on black

Fidhle007 :

Good choice!

Fidhle007 :

I have a customer with an A3 with some of the greatest paddle shifters I've ever used.

Customer:

When I get $1.98, I'll trick her up

Fidhle007 :

now if they could put that engine in the tiny car with the great paddles you'd have the greatest AutoX car ever made!

Fidhle007 :

Of course I'm sure it's been done already...

Customer:

MIne's 6-spd. Maybe my next one will have paddles.

Fidhle007 :

But the A4 is what I'd actually need, much better cargo capacity!

Customer:

Just enough cargo space to keep the passenger count to one!

Customer:

Hey Brendan, thanks for your help! Great chatting with you

Customer:

Pete

Fidhle007 :

Pete, good luck with your brakes!

Fidhle007 :

I'm glad I could help!

Fidhle007 :

Enjoy the car, I hope it makes it to 500k as well!

Fidhle007 :

Please leave me a positive rating when you get a chance!

Customer:

You got it!
