This guide details the process of replacing rear brake pads on a Yamaha Warrior 350. It covers the removal of caliper bolts, piston retraction using a C-clamp, cleaning components, and the reinstallation of new pads and bolts. Specific torque recommendations are provided for the bolts, and tips for dealing with seized or difficult components are included.

Quick Summary

To replace rear brake pads on a Yamaha Warrior 350, you'll need a 12mm socket, PB Blaster, a C-clamp, and brake cleaner. Loosen and remove the four caliper bolts, then use the C-clamp to retract the piston. Clean components, install new pads, and reassemble, torquing retention bolts to 10-12 ft-lbs and mounting bolts to 20-25 ft-lbs.

Frequently Asked Questions

What tools are needed to replace the rear brake pads on a Yamaha Warrior 350?

You will need a 12mm socket, PB Blaster for loosening bolts, a C-clamp to retract the caliper piston, a flathead screwdriver and hammer for minor adjustments, and brake parts cleaner with a rag for cleaning components.

How do you retract the caliper piston when replacing brake pads on a Yamaha Warrior 350?

Use a C-clamp to slowly compress the caliper piston back into the caliper body. If it's difficult, ensure the brake fluid reservoir cap is off and try manipulating the parking brake lever mechanism, as it can sometimes restrict piston movement.

What are the recommended torque specifications for the brake caliper bolts on a Yamaha Warrior 350?

The pad retention bolts should be torqued to approximately 10-12 foot-pounds. The main caliper mounting bolts can be tightened a bit more, to around 20-25 foot-pounds. Small tabs can be bent over the nuts of the retention bolts to secure them.

What should I do if the caliper piston on my Yamaha Warrior 350 won't retract fully?

If the piston is difficult to retract, check if the parking brake lever mechanism is interfering. Try manipulating this lever or temporarily disconnecting it. Ensure the brake fluid reservoir cap is removed to allow fluid to return to the reservoir.
