Automotive brake parts designed to replace worn bleed nipples, helping maintain braking integrity. Gain peace of mind during roadside repairs and routine servicing. Do the JUUDDENPARTS Brake Bleed Nipple Caps include the right sizes and protective features for long-term use?

⚡ At a Glance
  • Corrosion Resistance: Corrosion-resistant metal construction with rust-resistant plating
  • Best for: Motorcycle and electric-vehicle owners performing routine brake maintenance
  • Not ideal for: Calipers with non-metric or proprietary bleed fittings

Ten metal bleed nipples supplied in common metric thread sizes for replacement and repair. Flexible rubber caps protect tips and help preserve brake fluid quality.


Prevent brake-fluid leakage - thanks to direct replacement of worn bleeder screws

Damaged or corroded bleeder threads allow fluid to seep past seals; replacing them with correctly threaded metal screws restores the original mating surface and thread engagement. Precise metric threads match master cylinder and caliper ports for secure tightening.

Reduced risk of brake-fluid loss during and after servicing, improving safety and component longevity. Secure threaded fittings make routine bleed operations more reliable.

Keep fittings clean and sealed - with flexible rubber protective caps

Each nipple includes a pliable rubber dust cap that slips over the tip, shielding the bleed port from dust and contaminants. The caps maintain a barrier during storage and between uses to protect fluid and internal seals.

Cleaner bleed ports mean fewer contaminants entering the braking system, lowering corrosion risk and reducing the need for repeated fluid changes. Caps are especially useful for bikes stored outdoors or used in wet conditions.

Fast roadside repairs - thanks to multiple common metric thread sizes

The pack covers several standard metric sizes, including M6 x 1, M7 x 1, M8 x 1.25, M10 x 1 and M10 x 1.25, allowing a direct thread swap without re-tapping or adapters. Screws are designed for hand or simple spanner tightening, no specialist tools required.

Quick on-the-spot replacement is possible after minor damage or stripping, getting a bike back on the road without delay. Including several sizes reduces the need to carry multiple separate parts.
