BRAKE LININGS
REPLACEMENT
At intervals not exceeding 6 000 miles (10 000 km) the
wheels shall be removed and the thickness of the brake
lining5 checked. For the brake drums this is made through
the inspection holes. The brake linings should be ex-
changed at a thickness of 0.1 in. (2.5 mm), the friction
pads at 0.06 in. (1.5 mm) thickness of the very lining.
An exchange system is operative for compIm brake she:
Replacement of linings thus calls for exchange of the cry
tire shoe.
if linings only are to be changed, they must be ground in
a special machine to a radius of 0.010—0.012 in. (0.25.
030 mm) less than that of the brake drum in order to en-
sure perfect contact. The ends of the linings must not be
chamfered; the edge should be as sharp as possible,
1. Remove the old brake linings.
2. Wash the brake shoes in gasoline or kerosene and blow
clean with compressed air.
3. Place the new linings on the shoes and fix them with
two rivets in the center.
4. Fix the other rivets in turn, proceeding from the cen-
ter and out towards the ends. Stretch the lining well
to secure good contact with the shoe. Any clearance
left between the shoe and its lining may jeopardize
the function of the brakes and cause unwanted noise.
5. Grind the lining to a radius of about 0.010—0.012 in.
(0.25—0.30 mm) less than that of the drum.

To

be ground after riveting to a radius or ome~on12
in. (025-030 mm) less than that of the drum. This
is particularly important when the brake drum has
M machined. Special equipment is required for
W5 winding operation.

NOTE
To ensure optimal safety, use only genuine Saab
linings or exchange shoes.
