Manufactured from aluminum, it offers a balance of lightweight design and durability. This master cylinder features a straight bore type with a 19.05 mm diameter, optimized for precise brake fluid displacement. It includes two pistons and two ports, supporting dual-circuit brake systems commonly found in Mercedes-Benz vehicles. The inclusion of a dust boot and gasket or seal helps maintain system integrity by preventing contamination and fluid leaks. Note that this unit does not include a reservoir, brake booster, push rod, bleeder screw, or mounting hardware, so compatibility with existing components should be verified before installation.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis brake master cylinder is specifically designed for use with the following Mercedes-Benz models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMercedes-Benz C36 AMG\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz C220\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz C230\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz C280\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz SLK230\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIt is ideal for addressing issues related to brake fluid pressure and pedal feel in these vehicles.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by TRW PMK321\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpongy or soft brake pedal response\u003c\/li\u003e\n\u003cli\u003eBrake fluid leaks around the master cylinder\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency or inconsistent brake pressure\u003c\/li\u003e\n\u003cli\u003eBrake pedal sinking or failure to maintain pressure\u003c\/li\u003e\n\u003cli\u003eContamination or damage to internal seals causing hydraulic failure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the TRW PMK321 brake master cylinder, ensure the following:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eVerify compatibility with your Mercedes-Benz model and existing brake system components\u003c\/li\u003e\n\u003cli\u003eBleed the brake system thoroughly after installation to remove air and ensure proper hydraulic pressure\u003c\/li\u003e\n\u003cli\u003eInspect and replace any worn or damaged brake lines and fittings during installation\u003c\/li\u003e\n\u003cli\u003eUse appropriate brake fluid as specified by the vehicle manufacturer\u003c\/li\u003e\n\u003cli\u003eConfirm that the mounting holes align correctly with the vehicle’s brake booster or firewall\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eTRW manufactures the PMK321 brake master cylinder to meet strict quality standards, using high-grade aluminum and precision engineering.
