558404 Threaded Pushrod Multi-Mount Brake Master Pump

Product Overview
The 558404 Threaded Pushrod Multi-Mount Brake Master Pump comes with a threaded pushrod end and several possible mounting hole combinations. The threaded rod lets the installer fine-tune the free play between the pedal and the piston, while the multi-mount flange adapts to more than one vehicle platform that shares the same basic cylinder.

Core Functions
1. Threaded pushrod end – allows precise adjustment of pedal free play and secure lock-nut retention.
2. Multi-hole mounting flange – accommodates different bolt patterns found across related vehicle families.
3. Adjustable effective length – the threaded section compensates for small variations in pedal geometry.
4. Standard dual outlets – supports conventional dual-circuit plumbing.

Purchasing Motivations
1. One part number covers several platforms that share the threaded pushrod design.
2. Adjustable free play reduces comebacks caused by incorrect pedal travel.
3. Clear threaded end distinguishes it from plain-end pushrod units during picking.

OEM/ODM Services
OEM cooperation may include private-label packaging, logo printing and custom carton markings according to supplier capability. Production follows the approved specifications and quality standards.

ODM discussions can cover pushrod length options, thread details and packaging formats. Any change to the pushrod or hydraulic structure of the 558404 Threaded Pushrod Multi-Mount Brake Master Pump requires engineering review and validation because the component is safety-critical.

Customer Pain Points Addressed
1. Plain pushrods cannot be adjusted for free play – the threaded end solves this.
2. Single-pattern flanges limit application coverage – multi-mount holes expand fitment.
3. Incorrect free play causes spongy or high pedals – the adjustable rod lets technicians set it correctly.
