Porsche 991: Checking Brake Fluid

This is first in a short series of posts covering brake fluid service procedures for the Porsche 991 model line...

Checking Brake Fluid

Flushing Brake Fluid (replacing)

Bleeding Brake Fluid

All of the procedures I cover follow the official Porsche NA Work Manuals, to which I provide reference with each post.

So let's get on with it!

First up is a very basic How to Check your brake fluid level in the 991.

NOTE:

• The brake fluid level must not exceed the MAX marking.
• Check brake fluid quality. Use only new DOT 4 brake fluid.
• Brake fluid can be ordered using the Porsche Electronic Parts Catalogue (PET).
• The brake fluid reservoir is located under the cover that is fitted over the brake components (brake booster, brake master cylinder and hydraulic unit)

The brake fluid level can be checked through the opening in the cover (arrow) just forward of the (LHD) drivers position.

The brake fluid level should be between the MIN and MAX markings (shown below) which are marked on the sides of the brake fluid reservoir.

1.  If the brake fluid level has to be corrected, move the protective plastic cover  as shown below into the service position to expose the brake fluid reservoir.

     1.1  Lift up the cover and engage the yellow support in the luggage compartment lid.

2.  Correct the brake fluid level (see post Flushing Brake Fluid).

3.  The cover is fitted in reverse order. 

The above details and illustrations are from the official Porsche Work Manuals for the 991 platform.  In this case the document you should obtain is "WM 470801 Checking brake fluid level"
