Why swap? The GTI utilizes 286mm rear rotors (solid), just 2mm smaller than the rabbit front rotors (288mm vented). Everyone has heard about the quick wear on the Rabbit rear brakes. However, the GTI's do not appear to have this problem. So at the cost of a few extra unsprung pounds you get longer brake pad/rotor life and shorter braking. Just like the front brakes the GTI and Rabbits share the same pads and calipers, the only difference being the rotor and caliper carriers.

Difficulty rating 4/10 If you have the right tools its fairly simple.

A couple of things to note.
You cannot remove the rear calipers with the ebrake on. Use wheel chocks to stop the front wheels from moving and leave the car in 1st gear (manual) or park (automatic).
You'll only need to do about 1/2 of what is shown if you are swapping the stock rotors/pads for a rabbit.

Tools required.

Jack
14mm Triple Square
3/8 in drive breaker bar
T30 bit
17mm deep weld socket and appropriate ratchet
caliper piston compressor kit
$99 tool rental at Advanced Auto Parts(fully refundable)
$55 tool rental at Autozone (fully refundable)
$20 (not including tax/shipping) to purchase from Harbor Freight (larger kit is $35)

My final price from Harbor Freight was $30.40

GTI swap additional tools
13mm socket w/ ratchet
15mm box/open end wrench
tin snips

I'm starting this off easy by breaking the torque on the lug nuts, jacking up the rear control arm then removing the wheel/tire.

Locate the 14mm triple square bolts.
Image


Curse the skies in anger when the torque finally breaks and you rack your knuckles.

Loosen bottom bolt.
Image


Remove top and bottom 14mm triple square bolt and wiggle caliper loose. (Note, you cannot remove the caliper with the ebrake on.)
Image


brace the caliper on something so as not to put any undue stress on the brake lines.

Using the T30 bit remove the screw holding the rotor.
Image


Remove the rotor and note the 3 T30 screws holding the dust sheild. (Not required to remove for Rabbit brake replacement.)
Image


Destroy the dust shield.

Unbolt 3 T30 screws and remove shield

Admire the caliper and carrier. Note 13mm and 15mm sizes
Image


Loosen carrier/caliper bolts

Once the piston is compressed install the GTI carrier (if applicable) and install the new pads.
Image

Image


Install the rotor utilizing the T30 bolt again, and the caliper/carrier using the 14mm triple square bolts. (Be aware of the ABS sensor wire/connector. You do not want to have to replace this if you crack it with the breaker bar.)

Reinstall wheel/tire

Lower jack to torque down the lug bolts fully

Dont forget to pump the brake pedal to expand the caliper piston. You know it when the pedal gets hard. You also might want to let the car roll down the driveway a bit and then slam on the brakes. If you notice any liquid on the wheels, brakes or concrete you might have broken a brake line.

If you jack it up by the control arm all you're doing is compressing the suspension. Same as if you were driving around corners. I'm not lifting the whole car up by the arm, just enough to get the tire off the ground. This will also keep 3 wheels on the ground so you're working from a decently stable platform.

As far as the carrier/caliper question. I just found it easier to pull the caliper off than try to wiggle all of the tools behind the hub rotor and all of that.

Yes I do have GTI front rotors. However, I didn't think to get the weights of the rotors and carriers when I was messing with it.

No dust shield in the rear?? Ehhhhhhh......

ECS sells a kit that includes the carriers and rotors. Otherwise you'd have to get them from someone upgrading their GTI. They are pretty pricey purchased separately.

But you have a mkv again!

Bed in varies by rotor/pads. The two most common procedures are 1) moderate driving for 400-500 miles while the pads/rotors develop a nice relationship, go out on a couple of dates, then hopefully at the end of the 500 miles end up with a nice even surface between them. (avoid heavy braking) 2) Moderate slowing method. Varies from manufacturer to manufacturer. Accelerate to 30-40mph and gradually apply the brakes to slow to around 10 mph. Repeat this process several times allowing the brakes to cool between each braking session.

I like # 2. I start the procedure and drive for about 4 miles. Upon returning the customer is informed about proper break in (same as new vehicle) and away they go.

The GTI rears are the same size as the Rabbit fronts, so I don't think fitting a 15" steelie on there should be a problem. Though we'll let Hans test it out for us :)

It doesn't look like you used a jack stand. You may want to consider it. Cars are very heavy when they land on you and jacks do seep or fail.

This is true, but he wasn't lifting from the frame, he was lifting from the rear control arm.
