MCS Master Cylinder Rebuild Kits

13 products — part of all Master Cylinder Rebuild Kits

MCS master cylinder rebuild kits give you a practical, cost-effective route to restoring full brake performance on your Harley-Davidson without replacing the entire master cylinder assembly. The MCS range covers front and rear master cylinders across Sportster models from 2004 through 2022, FLT Touring machines from 2008 onwards including Trikes, and older 1972–1981 H-D applications, so both classic restorers and owners of modern bikes will find the fitment they need. Each kit contains the seals, pistons, and associated hardware required to return lever feel and hydraulic pressure to factory specification, making them an efficient choice for routine brake maintenance or addressing a weeping master cylinder before it becomes a safety issue. MCS brings the same broad-coverage catalogue philosophy that defines their brand to this brake system category, ensuring riders can source a quality rebuild solution alongside other service parts. Available through Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, these kits offer UK riders a dependable, well-priced alternative to full master cylinder replacement.
