Front brake master cylinder rubber

Brembo master cylinder, has a rubber dust cover on end of pushrod. Mine has split and in bits. Any ideas on what could be used, the Honda part number is 45504MAK 003. Rubber dust boot. But is over £9 plus postage  . So any ideas of a substitute would be much appreciated

Got this sorted used an old rubber plug cap, the end that takes the HT lead. Cut a piece  off and fitted perfect   Think the price of genuine Brembo one was silly  But sorted now.

Iirc the price of the master cylinder kit with spring, circlip, piston and rubber boot is about £27. Does make the brake feel better.

Btw, if anyone is having the mystery "lever going all the way back to the bar" thing, despite clean fluid and no leaks...its because you've the wrong brake lever fitted. The difference between the levers for Nissin and Brembo master cylinders is small but causes the above.
