Brakes questions

Unread post by muttero » January 9th, 2017, 2:19 pm

Hi friends,

I have doubts regarding the brakes. I would like to know if anybody knows the capacity of brake fluid of the master cylinder. I am asking this, cause I am planning to replace all the fluid of the system, and it is an important issue, as there is no brake fluid deposit, and when bleeding, you need to be sure there is enought fluid on the master for avoiding air to enter in the system... or is there any other way or tool to do so???

many thanks for your help

Your very best tool for this job is having friends to assist you (or at the very least, cooperative associates) ....and patience.

Along with that, a suitable funnel and a flashlight or a clean screwdriver to use as a dip-stick. Overfilling a MUTT's master cylinder means silicone fluids on the driver's side floor which is not the best place to have a slippery surface.. Ask me how I know. :roll:

If your help is new to all of this, brief them on what to do, what to expect and what not to do.

Just add brake fluid as you go and make sure the person operating the brake pedal eases it to the bottom of the stroke, rather than jamming it.

Work one bleeder / wheel cylinder at a time.

Starting at the right rear, left rear, right front, left front. You should not need more than a quart all told. You will use the most on the first bleed of the right rear since it has to fill the entire rear line and the line and cylinder to the right rear brake. After that all you are filling is the short line to the left wheel and cylinder. With the front you will use about the same for each side since the split is down on the frame.
