Brake Fluid Reservoir
Fig 58. Brake fluid reservoir.
1-
fluid reservoir, 2- cap, 3- pusher,
4- inspection lamp socket
Every 10,000 Km check the fluid level in reservoir 1 (Fig.
58), which should be as high as the lower edge of the filler
neck with cap 2 installed. Add only brake fluid Hesa or
ToML. Depress pusher 3 on the reservoir cap to check the
fluid level transmitter for proper functioning; with the ignition
switched on the warning lamp should be constantly alight. It
is recommended to replace the brake fluid after 5 years of
operation.
Flexible brake hoses
Every 10,000 Km, starting from 30,000 Km check condition of the brake hoses and replace
them with new ones, if minor cracks are detected on the sheathing or bulges appear on the
hose when the brake pedal is pressed.
Front Brakes
Every 10.000 Km check the condition of brake shoes 6 (Fig. 59). To remove the brake shoes
take out cotter pin 8 in the brake upper part; holding pressure lever 10, take out axle 7 and
remove the lever; shift upwards calliper 4 complete with cylinder block 1 until the lower
pressure lever is released, and remove the calliper with the cylinder block from the brake disc.
Replace the brake shoes if thickness of the friction pads is reduced to 1.5 mm. If the brake
shoes are removed for purposes other than replacement, mark them to reinstall the shoes in
their places.
Before installation of the brake shoes, make sure that brake disc 5 is not damaged nor deeply
scored. Replace the disc if it is worn to a thickness below 9.5 mm.
To install the brake shoes push the pistons as deep into the cylinders as possible. When
doing so see that the protective rubber seals of the pistons are in their sockets and are not
damaged; replace the seals, if necessary.
