Cannot get brake fluid pressure to bleeders

Hello my name is Dave.

Let's start by making sure all the steps to replacing a master cylinder are performed properly.

Here is a link to our tutorial on replacing a master cylinder:

Another thing we need to check is if the bleeder is clogged, a common problem especially if the cap that goes on the end of the bleeder is missing. I usually take a small drill bit and clean them out however they are not at all expensive so you may want to consider replacing the one that isn't allowing the fluid to flow. The easiest way to check this is to simply remove the bleeder completely and see if fluid flows. I hope this leads you to the solution to your problem.
