24 Apr Tech Tuesday: Why Would a Hydraulic Brake Lock Up?
One concern that so many women (and guys) have with owning a bike is the basics of fixing it, or how to do basic road side repairs. I do recommend that as an avid cyclist even with some mechanical skills that you should become best buds with your local mechanic (beer or ice cream works well.) I also want women to feel empowered and to have a better idea of what they are talking about. Tech Tuesday is the remedy for common tech questions!
Question of the week from Facebook: Why would my rear hydraulic brake be locked up after sitting for a month?
In my many years of riding I’ve never had a hydraulic brake lock up on a personal bike, but have seen it happen on a few customers bikes that they drag in with the wheel stuck and not rolling!
The above can happen for many reasons, all of them are prevented with proper cleaning and servicing your brakes just like you would your car!
- A blown seal can cause your fluid to not stay in the chamber it belongs in, and pushing the pistons to the “on position”
- Dirt or surface rust can make your pistons also get stuck. This happens the least, but cleaning your bike every once in a while can prevent this
- Dramatic change in temperature. If you have any air in your hose lines it can expand in heat, this can cause your pistons to also get stuck to the “on position.” This can be prevented with proper bleeding of the brakes.
