2. INTRODUCTION & SPECIFICATION
Robust, magnetic gauge mounts onto hub or brake disc for quick and accurate measurement of camber and castor angles. Large
adjuster knob for convenient zeroing of bubble during castor angle measurement. Graduated from +6° to -6°.
3. MEASURING CAMBER ANGLE
NOTE: Before proceeding to check the camber, first calibrate your gauge using one of the following methods:
a. Clamp a good quality spirit level, with transverse bubble, so that the long faces are vertical.
Place the magnetic face of the gauge onto the vertical face of the spirit level and adjust the gauge thumbscrew until
the gauge bubble is centred on the 0° mark.
b. Use a known true vertical surface to place the gauge against and adjust the bubble to zero.
NOTE: You must have a flat machined surface at 90° to the spindle in order to use this gauge. If using the brake discs ensure
there are no ridges and that the discs have even wear. Preferably use new discs.
3.1 To Check Camber With Wheels On.
3.1.1 Ensure your vehicle is parked on a flat level surface, the tyres are inflated to the correct pressure and the rear wheels
are chocked.
3.1.2 Having removed any wheel trims, place a straight bar across two flats of the wheel trying to keep as close to the 6
o’clock position as possible (Fig. 1). Ensure the wheel has no dents where you are placing the bar.
