Lotus Service Notes
2. Before replacing the pads, inspect the calliper for any signs of fluid leakage from a piston seal or joint,
and replace the calliper if any such signs are evident. Clean the pad recess in the calliper taking suitable
precautions to protect from dust inhalation.
3. If refitting the existing brake pads, refit each pad in the same position as originally fitted.
Pad securing pin
4. If fitting new pads, the pistons must be pushed back into the calliper to provide the necessary clearance.
This action will return fluid to the master cylinder such that some fluid may need to be removed in order
to prevent overflowing. Take care to avoid damaging the brake disc surface, or distorting the disc.
5. Position the pads in the calliper, and insert the upper pad retaining pin from the outboard side. Secure
with the split pin.
6. Fit the anti-rattle spring into position with the side tangs pressing against the top end of the pad backplates,
and the centre tang beneath the retaining pin. Insert the second pad retaining pin into the calliper,
passing over the lower central anti-rattle spring tongue.
7. Before driving the car, press the brake pedal several times to bring the pads to their correct running
position. Top up the master cylinder reservoir if necessary to bring the level to the top of the 'MAX' mark.
8. Ensure the customer is made aware that maximum braking efficiency will be achieved if, for the first few
hundred miles, needless heavy braking is avoided, and the brake pads are allowed to 'bed in' fully before
being used to their full potential.
JJ.5 - REAR BRAKE PAD REPLACEMENT
Pad thickness may be checked after removing the road wheel, without disturbing the calliper.
Standard pad thickness (excluding backplate);
Minimum pad thickness (excluding backplate);
If the thickness of any pad is below the specified minimum, the axle set of pads should be renewed. Note
that the pad backplates are marked T 4139 and are factory fitted with anti-squeal overlays.
