    Much to my consternation my Sealey vacuum pump has disintegrated internally and needs new seals. I found this out this morning when I decided to replace the brake fluid on my rear calliper. So I had to come up with plan B. I got the top of a spray bottle and shoved the stalk down the rubber tube and ran a tie wrap around it to seal it. Massaging the trigger rapidly done the same job as my now deceased pump. So anyone can make a DIY pump by using a long length of clear tubing which would hold a reservoirs worth of brake fluid so you wouldn't need the tank as shown on my set up. I daresay a bit of rubber tubing at the end would make it more feasable to seal around the stalk as it will be more flexible.

    Big syringe here....

    But to me "bleeding brakes" is more of an exclamation than a maintenance task

    Fit some speed bleeders. They work brilliantly, much better than a vacuum pump. They look like standard bleed nipples with a one way ball & spring valve inside them. Literally just attache a clear peice of tubing to them, crack open the bleed nipple and keep pumping the brakes until no more air comes out, then close and repeat for the rest. My brake lever hasn't felt as firm as it is now since I got the bike. Definately worth the money and saves a load of messing around.

    Didn't know these existed but we'll worth the . Only trouble is working out the size you need before ordering!
