1
00:00:00,000 --> 00:00:07,458
<b>Caution: </b>Brake shoes and the linkage design are matched for proper braking according to locomotive weight.

2
00:00:07,458 --> 00:00:12,792
Do not replace composition type brake shoes with cast iron shoes.

3
00:00:12,792 --> 00:00:21,167
Failure to use the proper replacement shoes may result in over-braking, under-braking, or an unbalanced braking condition.

4
00:00:21,167 --> 00:00:30,458
5. Install a new shoe in the brake head, line-up the keyway, and then drive the retaining key to seat tight in the keyway.

5
00:00:30,458 --> 00:00:35,042
6. Check the brake shoe for a tight fit in the brake head.

6
00:00:35,042 --> 00:00:42,292
<b>Note: </b>If the shoe is loose with the key tight in the keyway, the brake head is probably worn and should be replaced.

7
00:00:42,292 --> 00:00:47,500
<b>Note: </b>Newly installed brake shoes must hang true in the brake head.

8
00:00:47,500 --> 00:00:57,417
Brake head pins must be snug enough to keep the top end of the brake shoe from flopping onto the wheel, but loose enough to allow the shoe to conform to the wheel surface.

9
00:00:57,417 --> 00:01:03,708
The wheels should be free to move up and down in relation to the truck frame and the brake shoes.

10
00:01:03,708 --> 00:01:13,333
7. Adjust the manual slack adjuster as required, then reinstall any pins that were removed and lock them into place.

11
00:01:13,333 --> 00:01:17,000
8. Open the truck air cut-out cock.
