Measure and record the brake spring dimensions before disassembly.

• A. Measure and record the brake spring dimensions before disassembly
• B. Lubricate and inspect
• C. Replace before disassembly
• D. Ignore before disassembly

Answer: (A)

Measuring and recording the brake spring dimensions before disassembly gives you a precise reference of the original spring geometry. This is crucial because springs can wear, deform, or change length with use, and once the brake is taken apart you might lose the exact pre-disassembly dimensions. Having the measurements lets you verify that any replacement matches the original and ensures the springs are reinstalled with the correct orientation and tension, preserving safe and proper brake function. While lubrication and inspection matter, they don’t establish the reference data needed for correct reassembly; replacing springs before disassembly isn’t necessary, and ignoring the step isn’t acceptable for safety.
