Product Overview
The 5489036 Offset Large-Capacity Brake Master Cylinder places the fluid reservoir to one side of the cylinder body rather than directly on top. The offset position creates room for a larger tank while still clearing nearby components. The result is greater fluid volume without raising the overall height of the assembly.
Core Functions
1. Offset reservoir placement – shifts the tank sideways to free vertical space and allow larger capacity.
2. Increased fluid volume – larger tank extends the interval between fluid top-ups.
3. Side-clearance packaging – avoids interference with boosters, wiring or body panels on the original vehicle.
4. Standard dual outlets – supports the dual-circuit layout of the listed applications.
Purchasing Motivations
1. Larger capacity reduces low-fluid complaints on vehicles with long brake-line runs.
2. Offset design solves packaging problems that a centered tall tank cannot.
3. Distinct side-mounted silhouette is easy to identify in inventory.
OEM/ODM Services
Custom packaging highlighting the offset large-capacity feature is available. Changes to offset distance or tank volume require engineering review and validation to keep packaging and capacity correct.
Customer Pain Points Addressed
1. Centered tall reservoirs hit the hood or bulkhead – the offset layout avoids that conflict.
2. Small tanks need frequent topping-up – the large-capacity design reduces the frequency.
3. Wrong offset direction causes interference – the original side is retained.
FAQ
Q1: Which side is the reservoir offset on the 5489036 Offset Large-Capacity Brake Master Cylinder?
It follows the original vehicle design; always compare the side orientation against the old part before installation.
Q2: Does the larger tank change the bleeding procedure?
No. Bleed as usual, keeping the reservoir the highest point in the system.
Q3: Will the offset tank clear the brake booster?
On the listed applications the offset was designed to clear the booster and surrounding parts.
