INSTALLATION
GUIDE
FOR DISC BRAKE PADS

PREPARATION

| pliers
---|---
| wide screwdriver
| cotton swab
| allen key 5 mm, torx 10 (Magura), allen key 2,5 mm (Avid)
| matching brake pads with return spring and safety pin
| oil possibly a few drops of brake medium (Mineral oil for Shimano, Magura/DOT for Avid)

UNLOCK PADS
Disassemble both calipers for better handling. On (some) Shimano brakes, open the safety pin and pull it out. Avid and Magura always use screw pins here.

RESET THE PISTON
Use a wide screwdriver to push both pistons and the old brake pads completely back until they have reached their zero position. This makes room for the new thicker pads.

REMOVE OLD PADS
Only now remove the worn pads together with the return spring. Caution: The pads are asymmetrical. Note or mark the installation position of the pads when removing them.

CLEANING
Go over piston surfaces, seals and the inside of the brake caliper with cotton swabs soaked in alcohol or white spirit. This will remove greasy abrasion that can affect the mechanics.

POSSIBLY LOOSEN THE PISTONS
Drip, preferably with a syringe, a few drops of that respective brake fluid onto the sealing rings of the brake pistons. This makes the pistons run more smoothly.

PACK NEW PADS
Fit new pads and their new return spring (included in the pack) congruently.
Tip: The eyelet takes the safety pin and must match all parts.

ALIGNING
Carefully balance the package with your fingers and align the asymmetrical pads already in the correct position relative to the recess in the brake caliper.

INSERT PADS
Push the pads into their guides without canting. With Magura, the pistons are magnetized, the pad backs click audibly into position.

NEW SECURING
Now reinstall the pad securing.
Split pins should be replaced and are included with the replacement pads, you can reuse screws.
BRAKING IN
At least 30 moderate brakings from medium speed (approx.
30 km/h) almost to a standstill. Almost to a standstill therefore, so that no brake pad accumulations form on the friction surface, which can later cause unwanted vibrations (cause of noise). You should feel an increase in the braking effect during this step. If this no longer increases noticeably, the so-called friction layer is formed and this step is completed.
TIPS
Always hang or place your bike in an assembly stand to work in a stable and tilt-proof manner.
Only push back brake pistons together with the worn old pads:
Here, a pad surface scratched by the tool no longer does any harm.
In addition, some pistons are made of ceramic. Under pressure from a tool, this material can easily break.
Never introduce fluids foreign to the system (oil for DOT brakes and vice versa). This can irreparably damage piston seals.
