Autotech Brake Install


The installation included:

Autotech:

280mm (11") Cross drilled and slotted rotors - cad plated

226mm (8.9") Cross drilled only - cad plated

Mintex Red box pads

Stainless steel lines (6 total)

ATE Super Blue brake fluid

 

*Consult your Bentley manual for additional installation information.

Front Brakes

1. Remove the 2 caliper carrier bolts (13mm) and remove the caliper and pads. Support the caliper so you are not pulling on the brake line.  (if you are replacing your lines as well, remove the line from the caliper and cap the end with a vacuum line cap to keep the fluid in the system) 

2. Remove the 2 carrier bolts (17mm) and remove the carrier.

3. Remove the disc retainer screw and remove the disc.

Installation is the reverse of the above (make sure you use some lok-tite on the bolts) 

Rear Brakes

1. Remove the 2 caliper carrier bolts (13mm) and remove the caliper and pads. Support the caliper so you are not pulling on the brake line.  (if you are replacing your lines as well, remove the line from the caliper and cap the end with a vacuum line cap to keep the fluid in the system) 

2. Remove the 2 carrier bolts (T-25) and remove the carrier

3. Remove the brass cover to gain access to the "axle" nut.  Remove the cotter pin and the retainer.  The nut should be hand tight (24mm)  Pull the rotor off.

4. Press in your bearings and install the grease seals.  If you have ABS make sure you remove the old pick up from the rotor and install it on the new one (looks like a metal mesh cage)  Install the rotor and put the rear nut on hand tight.

5. The piston for the rear calipers is different then your standard caliper, as it goes into the caliper it turns as well.  There are several methods to do this (one being buy VW's special tool)  you can use a pair of plyer to turn the piston as you push in, use  screw driver in the slots of the piston to turn it and apply pressure to push it in, etc.

The rest in the reverse of the above.

Bleeding Brakes

To completely change your fluid, suck out what you can at the front reservoir.  Start at the front driver side caliper (nearest the master cylinder) and remove the old fluid until you see nice, clear, new fluid.  Then go the farthest point away from the master cylinder (passenger rear) and pull the fluid out until it's new and clean.  Work your way around the car ending at the driver's side front again. (driver side rear, passenger side front, driver front)  Then start the cycle again, this time to ensure you got out all the air in the system.  I used 5 repetitions at each corner (build pressure in the system, open the bleeder screw, watch for air bubbles, close the screw and repeat a total of 5 times, each corner)
