Brake Bias Valves
SESSION LENGTH This lesson has been designed for a one hour session; however the teacher can adapt the lesson to suit their needs. However, it is recommended that the session last no more than two hours. STUDENT COHORT This session is aimed at students studying a Level 3 Automotive Engineering course. The students should have previous background knowledge with regards to vehicle braking systems and a basic engineering background. They should have all studied at least to a GCSE level. It can also be used as revision aids for students studying at a higher level, or to anyone with an interest or who are in industry. RESOURCES This resource includes a video, a Power Point presentation, animations, course notes, and worksheets. AIM • The aim of the lesson is to recognise the need for brake bias (proportioning valves) within a vehicle braking system OBJECTIVES At the end of the session, students should be able to: • Identify the location of a brake bias valve • Explain how a brake bias valve operates • Evaluate its performance on the vehicles braking system OVERVIEW OF SESSION Introduce the topic’s aim and objectives by use of the PowerPoint Presentation; continue then to introduce the needs of a brake bias valve via the PowerPoint, draw on the fact that it is normally used within the race industry. With the use of the animations, demonstrate the operation of the brake bias valve. If possible, show the brake bias valve on a vehicle. Alternatively, components can be brought into the classroom; the video can then be shown at this point. The research activity is given in order for students to build up their knowledge and understanding on the subject, and how they would apply it to a given situation. The worksheet is designed for individual work to establish that learning has taken place; a review of the answers should be done ASAP after the students have completed it.
