Brake pads are accessible with the wheel off without removing the brake caliper. Parts needed when replacing the pads may include a kit with pins and springs and a packet of brake grease.

==Removal==
The Saab OEM springs are better fit and quality than the most popular aftermarket kit made by Scantech.

===Brake Pads===
Pads can be removed using pliers or a pad removal tool. Minimum pad thickness is 5 mm, (not including the backing plate). The pads may stick on a ridge built up on the rotor due to wear, or because rust and brake dust collects inside the caliper, and may have to be pushed side-to-side before they come loose. The caliper cavity can be cleaned out with a wire brush once the pads are out.

===Caliper Pistons===
The pistons have to be pushed into the caliper to make room for the new pads. According to the Haynes manual, the orientation of a cutout in the piston should be checked, and if necessary rotated toward the bottom, so moisture can drain out properly.

===Pads===
Apply some brake grease to the back of the pads and insert them into the caliper. Insert the top pin as far as it will go by hand, then tap it in the rest of the way using a hammer.
