Brake Bleeding

Here's how I do it...

I start by removing the two philips screws holding the master cylinder's cap and taking the cap off.

Inspect the rubber seal under the master cylinder's lid while it's off. Make sure it isn't cracked or torn.

The stock brake fluid in a scoot is often nasty, so soak that up with some paper towels and clean out the master cylinder with a little brake cleaner on a rag.

Now fill up the resevior with fresh brake fluid.

Then place a catch pan under the brake caliper and open the bleeder valve a turn or so. You could also attach a length of tubing to the nipple on the bleeder valve and route it into a bottle to avoid any spills.

Once brake fluid starts to flow out of the bleeder, close it. Remember not to let your master cylinder run dry in this process. With the bleeder closed, fill the master cylinder with fluid and put the top back on with the two phillips screws.

Pump the brake lever a few times and keep it depressed while you open the bleeder valve. Brake fluid and air should come out of the bleeder. Close the bleeder and then you can release the brake handle.

Check the fluid level in the master cylinder and add if needed. Pump the brake lever a few more times. Hopefully you will feel the lever getting more firm. Once again, hold the brake lever while you open the bleeder valve. If it wasn't already, squeeze the brake lever until it is all the way depressed and then close the bleeder valve while still holding the brake lever. Once the bleeder is closed, check the brake fluid again. Repeat this process as necessary to get a firm brake lever.
