Brake pedal assembly ACURA NSX 1997 Service Repair Manual

4-2
For the details of lubrication points and types of lubricants to be appl\
ied, refer to the illustrated index and various work
procedures (such as Assembly/Reassembly, Replacement, Overhaul, Install\
ation, etc.) contained in each section.
*1: Always use Honda Manual Transmission Fluid (MTF). Using motor oil can \
cause stiffer shifting because it does not contain theproper additives.
*2: Always use Honda ATF-Z1 (ATF). Using a non-Honda ATF can affect shift \
quality.
*3: Always use Honda Heavy Duty DOT3 Brake Fluid. Using a non-Honda brake fl\
uid can cause corrosion and decrease the life of the system.

Inspection and Adjustment

Brake System Rubber Parts and Brake Booster

Brake Booster

Check brake operation by applying the brakes.

If the brakes do not work properly, check the brake

booster. Replace the brake booster as an assembly if

it does not work properly or if there are signs of leak-

age.

Piston Cup and Pressure Cup Inspection

• Check brake operation by applying the brakes.

Visually check for damage or signs of fluid leakage.

Replace the master cylinder as an assembly if the

pedal does not work properly or if there is damage

or signs of fluid leakage.

• Check for a difference in brake pedal stroke

between quick and slow brake applications.

Replace the master cylinder if there is a difference

in pedal stroke.
Brake Hoses

Visually check for damage or signs of fluid leakage.

Replace the brake hose with a new one if it is dam-

aged or leaking.

Caliper Piston Seal and Piston Boots

Check brake operation by applying the brakes.

Visually check for damage or signs of fluid leakage.

If the pedal does not operate properly, the brakes

drag, or there is damage or signs of fluid leakage,

disassemble and inspect the brake caliper. Replace

the boots and seals with new ones whenever the

brake caliper is disassembled.ProCarManuals.com
