🔧 Brake Safety & Install Tips
- Professional Install Advised: Brakes are life-critical components. If you are unsure about installation or bleeding the system correctly, please use a professional, accredited UK garage. Incorrect installation *will* cause total brake failure.
- Use Fresh Fluid: Never reuse old brake fluid. Always bleed the system with a fresh, sealed bottle of DOT 4 fluid.
- Aesthetics: Finish may be silver or black depending on batch. Check the gallery picture for style confirmation.
