Manual brake setup and operation
The parts of a hand-operated brake and the terms setup depends on, how the metal sets capacity, setback and springback, setting up and proving a brake to form the FlashDraft Drip Edge, and how to diagnose uneven bends before a piece ships.

Manual brake setup and operation: principles and terminology
What a hand-operated brake does, the parts every operator must know by name, the terms setup depends on, and where the danger is.
You will be able to: Name the parts of a manual brake, define setback, capacity and springback, and state where its safety limits are.

Manual brake setup and operation: materials, standards and design constraints
Why capacity changes with the metal, how thickness sets the setback, what drives springback, and the limits of the machine and the coating.
You will be able to: Read a brake's capacity for the metal in hand, size the setback from the thickness, and allow for springback, machine limits and the finish.

Manual brake setup and operation: methods and worked application
Setting up a shop brake step by step, then forming the FlashDraft Drip Edge in 24 ga galvanized: setback, marks, bend order and limits.
You will be able to: Level and set up a brake, set setback and clamping pressure, prove them with test bends, and plan and form a FlashDraft profile.

Manual brake setup and operation: defects, verification and case study
Reading a bad bend: open in the center, closed at one end, a creeping hold-down and marked paint; then a case worked through and the checks before a piece ships.
You will be able to: Diagnose uneven bends from where along the length they go wrong, choose the manufacturer's correction, and verify the piece against the drawing.

Practical task
Plan and form the FlashDraft Drip Edge in 24 ga galvanized on a manual brake (or, without a brake, plan it fully on paper), then document it as a job packet a reviewer can check.
Hand in
- A setup sheet: brake make and model, its rated capacity, the material and thickness taken from the AFS material register, and the setback worked out by that brake's manufacturer rule
- The marked-up profile: bend lines measured from one end, each bend's turn and direction, the bend order, and where the sheet is turned over
- Test bend results at both ends of the brake, and any setback or pressure change made
- An inspection record: thickness, girth, every leg to the mold line, every angle at both ends and the center, and the finish
- A defect analysis for one bend that was off: where it was off, the cause by the manufacturer's troubleshooting, and the fix
Rubric
| Criterion | Meets the standard when |
|---|---|
| Sources | Every number on the setup sheet names where it came from: the register, the manual, or the drawing. |
| Setback | The setback is calculated correctly from the thickness by the stated manufacturer rule, with units. |
| Planning | Bend lines and turn-overs match the profile's bend schedule, the forming order lets each flange clear the clamping leaf, and any angle past the brake's stated maximum is closed by a documented method. |
| Verification | Angles are recorded at both ends and the center, and the girth agrees with the drawing. |
| Diagnosis | The defect analysis ties where the bend was off to a cause the manual lists, and shows the fix was proved with a test bend. |
| Safety | The packet notes the PPE worn and that hands stayed clear of the point of operation. |
