Description
Genuine Land Rover clutch master cylinder for Defender and Series 3 clutch hydraulic systems, replacing STC500100 and earlier part numbers 550732, STC100410 and STC100411. A worn master cylinder can leak externally or bypass fluid internally, causing a low or soft clutch pedal, poor clutch disengagement or difficulty selecting gears. The Genuine Land Rover cylinder restores the standard clutch hydraulic setup with the factory Genuine replacement part.
Related Parts
When replacing the master cylinder, the small pushrod adjustment and locking nuts are often corroded, seized or damaged after years inside the pedal box. Our Defender clutch master cylinder pushrod nut kit replaces all three nuts with new stainless steel fixings.

Genuine Land Rover Parts
Genuine Land Rover parts for Defender, Discovery and Range Rover models, including TD5 engine components, seals, switches, cooling parts, body fittings, drivetrain components and original service parts.
Genuine parts are supplied under the Jaguar Land Rover parts programme and identified as Genuine Land Rover on the individual product page. Check the part number, vehicle fitment and any engine, model or early and late split before ordering.
Genuine Land Rover parts from Twinwoods 4x4
Genuine Land Rover parts remain the benchmark where exact original specification, fit or appearance matters. The range includes complete components alongside the small seals, clips, bolts, switches and fittings that can be difficult to match accurately with aftermarket parts.
| Parts required | Examples in this range | Check before ordering |
|---|---|---|
| TD5 engine and fuel system parts | Injector seals, filters, timing chain parts, sensors, fuel pressure regulators and engine sealing components | Check the engine type, part number and any early or late TD5 fitment split |
| Cooling system parts | Thermostats, coolant hoses, expansion tanks, bleed screws and sealing parts | Check the vehicle, engine and original part number |
| Electrical parts and switches | Window switches, brake light switches, horn switches, relays and lighting components | Check the connector, vehicle model and part-number supersession |
| Body, trim and exterior fittings | Badges, clips, seals, caps, lock parts, fasteners and model-specific trim | Check model, position, side and colour where relevant |
| Axle and drivetrain parts | Oil seals, drain plugs, CV spacers, gearbox fittings and related hardware | Check axle position, transmission type and original part number |
When Genuine Land Rover is worth buying
Genuine parts are particularly valuable where a component has an exact moulded shape, electrical specification, sealing profile, finish or fitment that is difficult to reproduce consistently. They are also often the best answer for obscure clips, fixings and small fittings where an almost-correct replacement can create more trouble than the saving is worth.
Check the part number
Land Rover parts can look identical while using different dimensions, connectors or internal specifications.
Check the vehicle and engine
Defender, Discovery and Range Rover models often use different parts despite sharing an engine or component description.
Check early and late fitment
TD5 fuel, electrical and cooling components can change by engine generation, model year or original installation.
Check what is included
Some genuine components are supplied individually, while seals, fixings or related parts may be sold separately.

Can I fit a part and then return it?
Please check fitment and suitability before installation.
Please do not fit or attempt to fit a part unless you intend to keep it.
Once a part has been fitted or an attempt has been made to fit it, it may be marked, contaminated, damaged or otherwise unsuitable for resale as a new part. We do not operate a used-parts or bargain-bin section, so a fitted or damaged part can have very little resale value.
Where your handling has reduced the value of the goods beyond what is reasonably necessary to inspect them, your refund may be reduced to reflect that loss in value.

Warranty
Buy with confidence: all new parts sold by Twinwoods 4x4 include at least 12 months manufacturer warranty against defects in materials and workmanship under normal use.
Some products and brands may include a longer warranty period where this is provided by the manufacturer. Where applicable, this will normally be stated on the individual product page or covered by the manufacturer’s own warranty terms.
Warranty cover applies to manufacturing defects. It does not cover misuse, incorrect fitting, competition use unless stated, contamination, modification, damage during installation, normal wear and tear, or failure caused by an unrelated vehicle fault. For certain components, proof of professional fitment may be required.
Warranty claims may require the part to be returned for inspection and/or supplier testing before the claim is accepted. Any advance replacement is discretionary.
Warranty remedies relate to the part itself, meaning repair or replacement, or refund if those are not possible. Warranty does not cover labour, removal or refitting, diagnostics, consumables, travel or other incidental costs.
This warranty is in addition to your legal rights and does not reduce those rights.
