BRAKE MASTER CYLINDER FOR TRACTORS MASSEY FERGUSON

Brake Master Cylinder for Tractors Massey Ferguson

The brake master cylinder is a key component of the braking system on many tractors Massey Ferguson. This part number applies to specific models in the 5400, 6200, 6400, and 8200 series. For this repair, one important point must be taken into account when preparing the parts: the pressure accumulator 3789371M3 must be replaced at the same time.

What is the role of this part in the brake system?

The master cylinder converts the force applied to the brake control into hydraulic pressure within the system. On a tractor, it therefore plays a role in initiating and maintaining consistent braking. If it develops a leak, operates abnormally, or functions irregularly, replacing it restores the system’s control function.

This part must be selected with precision, as a brake master cylinder is not interchangeable between different setups without verifying the exact application.

Massey Ferguson s Affected

This master cylinder is designed for tractors Massey Ferguson in the following series:

• 5400 Series: applications on models 5425, 5435, 5445, 5455, 5460, 5465, and 5470.
• 6200 Series: for use on models 6260, 6270, 6280, and 6290.
• 6400 Series: compatible with several models from 6460 to 6499, including the 6497 Tier 3 and 6499 Tier 3 variants.
• 8200 Series: Applications on the 8210, 8220, 8240, 8250, 8260 LST, 8270, and 8280.

These designations are useful for quickly identifying the correct part, especially when several similar versions exist within the same series.

Important Consideration When Replacing

Replacing this master cylinder requires replacing the pressure accumulator 3789371M3 as well. This step should be planned in advance before opening the circuit or disassembling the brake components. Ordering both part numbers at the same time prevents interruptions during the repair and facilitates a consistent restoration of the entire assembly.

If your tractor has undergone a previous repair, also verify that the existing assembly is suitable for the intended application.

Useful guidelines for identifying the correct part number

To select this brake master cylinder, first verify the exact tractor model, then check for any variations in its designation. Suffixes such as Tier 3 or LST should not be overlooked. If you still have the old part, comparing it to its original part number is a good additional reference.

Before finalizing your selection, make sure your tractor is listed among the documented applications and, at the same time, order the accumulator 3789371M3 to ensure the repair is carried out under optimal conditions.

FAQ — Frequently Asked Questions

What is the purpose of this brake master cylinder on a Massey Ferguson tractor?

The brake master cylinder controls the pressurization of the brake system when you press the pedal. On compatible Massey Ferguson tractors, it therefore helps activate the hydraulic braking system. Replacement is necessary in the event of a leak, an abnormal pedal feel, or uneven braking.

Should the pressure accumulator 3789371M3 be replaced at the same time?

Yes, simultaneous replacement of the pressure accumulator 3789371M3 is recommended with this part number. This is important to ensure a properly functioning brake control system. If you are preparing for the repair, be sure to have both parts on hand before disassembly.

Which Massey Ferguson tractors are covered by this part number?

This part number is intended for several Massey Ferguson tractors in the 5400, 6200, 6400, and 8200 series. It specifically covers models such as the 5425, 6270, 6485, 6497 Tier 3, 6499 Tier 3, 8210, and 8260 LST. Always verify the exact model designation of your tractor.

How can I verify that this part is the right fit for my model?

The best way to verify is to cross-reference the part number you’re looking for with the exact tractor model and, if possible, the part number of the part already installed. Suffixes and variants matter—for example, Tier 3 or LST. If there’s a discrepancy in the part number, it’s best to confirm before ordering.
