In this video tutorial, I will show you how you can quickly pump the hydraulic brake on your mountain bike.
This procedure should be done regularly. The hydraulic fluid will gradually drain out of the brake. The brake on your bike starts to fail. The brake lever reservoir is leaking and needs to be filled with mineral oil.
In this video, we use a Shimano brand brake with mineral oil.
