Product Details
Brake Master Cylinder 1.14 Bore
,ISUZU 600P NPR75 Master Cylinder
,Aluminum OEM-Spec Brake Cylinder
Brake Master Cylinder 8-97314530-0 / 8973145300 is a verified replacement hydraulic pressure generator for ISUZU 600P, N900, NPR75, 700P, and NKR light trucks equipped with the 4HK1 (5.2L) diesel engine. This complete master cylinder assembly converts brake pedal force into hydraulic pressure, transmitting it to the wheel cylinders or calipers to decelerate or stop the vehicle.
The unit is defined by a 1.14-inch bore specification and is manufactured from aluminum for the cylinder body, providing corrosion resistance and dimensional stability in the brake hydraulic circuit. It serves as the heart of the hydraulic braking system — a piston-driven hydraulic pump that converts the driver's mechanical pedal input into hydraulic pressure.
- 1.14 Bore Specification: Multiple supplier catalogs list the 1.14 specification for this master cylinder family. Confirm the original unit's bore diameter before ordering — a mismatched bore alters pedal effort and braking balance.
- Cross-Platform Coverage (ISUZU + JMC + JAC): Confirmed for ISUZU 600P, N900, NPR75, 700P, and NKR, as well as JMC 1042 / 1062 and JAC 1040 / 1048 / 1040S. It is a cross-brand SKU serving mixed ISUZU/JMC/JAC light commercial fleets.
- Complete Assembly Scope: This listing covers the complete brake master cylinder assembly. The reservoir may or may not be included depending on the supply channel — confirm package contents at inquiry. It is not a repair kit or a bore-only component.

- ✓HS Code Verified: 851140100 — confirmed for the brake master cylinder classification.
- ⚠Reservoir Inclusion NOT Uniformly Specified: Some supply channels include the reservoir, while others supply the cylinder assembly only. Confirm package contents at inquiry — a missing reservoir immobilizes the vehicle.
- Sinking brake pedal at a stop: The pedal slowly creeps toward the floor while holding steady pressure — indicates internal seal bypass within the master cylinder.
- Spongy pedal that persists after bleeding: Air enters the system through a failed seal, and bleeding does not permanently remove the sponginess.
- Inconsistent pedal feel: The pedal may feel normal on one application and low or soft on the next, as internal seals intermittently fail to hold pressure.
- Brake fluid leak at the master cylinder body or pushrod end: External seal failure allows brake fluid to escape, often visible as wetness on the booster or firewall.
- Brake warning light illumination (without low fluid): A failing master cylinder can trigger the brake warning lamp even when the reservoir is at the correct level.
- Longer stopping distances / need to pump the pedal: As pressure retention degrades, the driver must pump the brake pedal repeatedly to build sufficient braking force.
Consequence of Ignoring Symptoms: A failing brake master cylinder is a direct loss-of-braking hazard. Internal seal bypass can progress from a slow pedal sink to complete loss of hydraulic pressure with no warning, particularly under hard braking or during a panic stop. On a loaded 600P or N900 commercial truck, replacement at the first sign of a sinking pedal or persistent sponginess is essential.

Because the reservoir inclusion and bore specification are critical, and cross-brand coverage spans ISUZU, JMC, and JAC, confirming the physical form, bore, and package scope on the first sample is strongly recommended before bulk commitment.
IMPORTANT: Brake system service requires professional expertise. The master cylinder is the primary pressure source for the braking system. Always refer to the ISUZU 600P / N900 workshop manual for the specific model. Improper installation can result in brake failure and serious injury. Bench-bleed the master cylinder before installation.
- 1Confirm the required part first: Verify the original master cylinder's bore specification, outlet thread, and whether the reservoir is to be reused. Compare the physical form to the replacement.
- 2Bench-bleed the master cylinder: Clamp the cylinder in a vice with soft jaws and bleed it on the bench before installation to reduce in-vehicle bleeding time.
- 3Disconnect the battery and brake lines: Disconnect the negative battery terminal. Place a drain pan underneath, disconnect the brake lines from the master cylinder, and plug the lines immediately to prevent contamination.
- 4Remove the old master cylinder: Unbolt the master cylinder from the brake booster. Note the orientation of the pushrod and any spacers.
- 5Transfer the reservoir (if applicable): If the replacement is supplied without a reservoir, carefully transfer the original reservoir and seals.
- 6Install the new master cylinder: Position the 8-97314530-0 unit, connect the brake lines, and torque the mounting nuts to the workshop manual specification. Do not over-torque the hydraulic line fittings.
- 7Bleed the brake system: Bleed the front and rear circuits according to the ISUZU procedure until clear, bubble-free fluid flows from each bleeder screw.
- 8Test pedal feel and brake function: The pedal should be firm and should not sink under sustained pressure. Road-test at low speed before returning the vehicle to service.
- Inspect brake fluid at every service — contaminated or dark fluid accelerates master cylinder seal wear.
- Replace brake fluid every 2 years or according to ISUZU schedule.
- Check for leaks at the master cylinder body, line fittings, and reservoir seal during routine inspection.
- Replace the master cylinder at the first sign of a sinking pedal or external leak — do not monitor a known-failing brake component on a commercial vehicle.
- Standard packing: Neutral packaging / wooden box / carton / pallet; customer-branded packaging available.
- Package contents: 1 × Brake Master Cylinder Assembly. Reservoir inclusion varies — confirm at inquiry. Mounting hardware and brake fluid are not included unless explicitly stated.
- Set options: Cylinder only (standard) / cylinder + reservoir (where available) — specify at inquiry.
- Suitable for: ISUZU 600P / N900 / NPR75 / 700P / NKR brake system repair shops, JMC 1042 / JAC 1040 service providers, light commercial fleet maintenance departments, spare parts distributors, and export wholesalers.
