Solution:

Explanation: Back stop brake can be used to prevent rotation of drum.

QUESTION: 3

### A self-locking differential brake and back stop brakes is same thing.

Solution:

Explanation: Back stop brake is other name of self locking differential brake.

QUESTION: 4

Band brake has complex construction with large number of parts.

Solution:

Explanation: Band brake has simple construction with small number of parts.

QUESTION: 5

Band brakes require _____ maintenance.

Solution:

Explanation: There is relatively less maintenance required as there are small number of parts and hence chances of brake going out of order is less.

QUESTION: 6

The wear of band brake is even.

Solution:

Explanation: There is uneven wear from one side to other side of the friction lining.

QUESTION: 7

Solution:

Explanation: Terminology.

QUESTION: 10

Disk brakes largely suffer from the problem of self-locking.

Solution:

Explanation: There is no problem of self-locking in disk brakes.
