What to quote
State the quantity of brake booster and the agreed assembly contents for each application. Identify pieces per set and any separately priced hardware before comparing quotations.
Nissan Navara · Brakes & Parking Brake
Identify the fitted brake assistance unit, mounting studs and pushrod arrangement. Compare vacuum fittings and master-cylinder attachment before accepting a replacement.

| Record | Details to retain |
|---|---|
| Assist architecture | Identify assist architecture from the vehicle and installed assembly, retaining readable labels. |
| Stud pattern and rod arrangement | Show stud pattern and rod arrangement in photographs and provide the dimensions needed to compare the interfaces. |
| Vacuum or control interfaces | Specify vacuum or control interfaces in the requested contents so offers refer to the same assembly. |
Do not treat a different assistance architecture as an equivalent round booster based on outer diameter.
For brake booster, keep the full chassis identifier and build record with the request. The Navara chassis and market guide separates D22, D40, D23 and D27 identification; neither NP300 nor Frontier naming alone proves compatibility.
When brake booster is quoted with related assemblies, use the brake and parking-brake orders guide to keep their requirements distinct.
Send clear overall and mounting or connection photographs. For this brake booster inquiry, retain stud pattern and rod arrangement; mark unknown dimensions instead of borrowing a number from a different generation. The OE and vehicle-identification checklist helps organize the information.
Treat every linked assembly as a separate order line from the brake booster; approving one component does not confirm the others.
Navara Vacuum Pump — retain engine and vacuum source and drive and lubrication interface for that assembly.
Navara Brake Master Cylinder — retain brake-assist system and bore and port locations and threads for that assembly.
State the quantity of brake booster and the agreed assembly contents for each application. Identify pieces per set and any separately priced hardware before comparing quotations.
Protect pushrods and prevent loads on plastic vacuum fittings.
Before approving the brake booster, agree sample and inspection requirements using the quality-control checklist. Return to the Navara component directory for other systems.
For brake booster requirements on other vehicles, compare the brake parts directory. Keep the Navara specification and every other approved model on separate order lines.
