Task in the afternoon

Brake shoes adjustment on VW 1302 Super Beetle far improved braking performance, the transition from rear to front became so smooth and braking power has increased.
Rear left side leading shoe had relatively excessive clearance, this was the reason to have said professional mechanic inadequate balance on pedal touching.

After minimizing the clearance between brake shoe and brake drum inner surface on all the wheels, the brake pedal position has come near to the driver.
However hard I may pay attentions to the adjustment, the work was not perfect enough to attain the result like professional's works.
This is not because of lack of capability but because of lack of experiences.
I knew again that the skills would be nourished by error corrections by myself.
