Road-test the Lotus and scan its brakes
We start with a drive to feel the judder, pull or noise at first hand. Steering and suspension parts near the wheels are inspected in the same check, since their wear can feel like a brake fault. Stored brake codes come off the car through a diagnostic tool next, and each code sets a repair.

Raise the car and measure pads and discs
An Emira goes up on the ribbed alloy pads under the front and rear of its chassis, and nowhere else. Each disc is measured at no fewer than 4 places, with the lowest reading checked against its stamped MIN TH value. Every pad gets its friction material gauged in the same pass.

Set the parking brake and retract the pistons
Before the rear pads come out, a diagnostic tool puts an electric parking brake in pad changing mode. Turning that piston back like a mechanical handbrake piston ruins its pressure nut or spindle. On the Emira's four-piston front callipers, all pistons go back at once with the right tool, and we watch the reservoir level rise.

Clean each hub face and fit the discs
Every hub face loses its rust and dirt to a scraper first. A rust speck just 0.05 mm across is enough to push runout beyond 0.1 mm. We then check runout against the 0.10 mm limit for cars, and recheck the hub and refit any disc beyond it.

Fit the pads as an axle set
The pads of both callipers on the axle are renewed at the same time, along with the pad springs. No grease or oil touches the friction faces of pads or discs, and we replace any part that has been contaminated.

Pump the pedal, calibrate and road-test
We pump the pedal until it reaches its usual travel, then check and correct the reservoir level. Calibration of an electric parking brake follows, by diagnostic tool. On the final road test we listen and feel for noise and vibration, without stabbing the pedal or holding it beyond 3 seconds.
