Diagnose and repair a soft brake pedal and grinding noise
You are a light vehicle technician in the service workshop.
What has happened
Lena Bergstrom's 2018 sedan arrives on RO-26-4520 with a soft brake pedal and a grinding noise from the front when braking. The Customer Care Manager has flagged the job as safety related and the customer has asked for a call before any work beyond the inspection fee. Your job is to inspect and diagnose the braking system, find the cause of both symptoms, and prepare a written quote with the reasons for each item so the service advisor can obtain authorisation. The quality and warranty policy requires a second technician to check brake work before release, and the customer service policy means the vehicle cannot be released with an unsafe defect without the Service Manager's approval.
Deliverables
- Repair order with diagnosis, cause and correction recorded
- Completed repair quote with priorities and customer authorisation recorded
- Quality check and road test sign off
- Photographs or description of worn components

Evidence guide
Check that the diagnosis separates the two symptoms and identifies a cause for each, that the quote gives reasons and priorities, that no work beyond the inspection was started before authorisation was recorded, and that the quality check was completed by a second person. Brake cleaning method and waste handling are also assessable.
