Front Brake Caliper Assembly - Yamaha TZ/RD250/350 RD400 TX/XS500 TX/XS650 TX/TZ750 Reproduction Yamaha front brake caliper assembly. This caliper comes pre-assembled as shown in the photo for easy installation. This presents a solution to these questions...."what do I do if my piston is heavily pitted and so is the inside of my caliper?" or "my pads are toast, my bleeder valve is seized and so is my piston!" Yes, some of us just start cleaning, soaking and scrubbing all the parts and replace individual parts such as the piston, seal and bleeder valve but if you want your caliper looking and working like new and you want to save a lot of time, get the complete caliper. Finish the job in minutes rather than hours!Replaces Yamaha part number: 306-25810-0A-00Includes all parts shown in the photo and brake pads.
