How To Bleed The Brake System On Your 2009-2010 Honda CRF450r.
The Tools You Will Need Are:
- 8mm Wrench
- Clear Tubing
- Catch Pan
- Shop Towels
The only part you will need is a bottle of fresh DOT 4 brake fluid.
If you don’t have your brake fluid yet, you can get some HERE (link to RockymountainATVMC.com).
Bleeding your brake system is a simple procedure, but does require patience.
You can bleed your brakes either manually, or with a hand held vacuum pump.
The vacuum pump is faster, but I don’t take it to the track, so we’re going to stick with the manual method.
Remember! Brake fluid will damage your pads, so keep your shop towels ready!
Bleeding Your Brakes
The bleeding procedure is the same on the front and rear brakes.
The brakes are a sealed system, so installing the reservoir cap will work against the bleeding process by creating a vacuum in the reservoir.
If you pump the brakes with the valve open, you will draw air back into the system.
If you are replacing fluid, repeat this process until fresh brake fluid is pumped from the caliper.
Throughout the bleeding process, keep an eye on your fluid level. If you let the reservoir drain, you will introduce air from the opposite side of the brake system, and you need to start over.
