993 Brakes

Lots of new parts. Coated Zimmermans/Textar's pads and all sensors.


Two before pictures  front and back



 I decided to pull the Calipers off to inspect and properly clean. It was time to replace the brake fluid anyway. It has been said that the fluid absorbs 1% of water per year. It has been three years.













 I decided after much research to reuse the Spiders Porsche installs. They are easily removed with a razor blade . Lacquer thinner does a great job of removing the original silicone adhesive. Just use new silicone to apply to new pads.










The most critical cleaning step is to get the sliders surgically cleaned and polished with emery paper,. This is best done by removing the sliders first. They are installed with Locktite. Go slow and use the right tool. Re install with Locktite.






Here is a before and after polishing


I like to use WD 40 for cleaning . It is a poor lubricant but great safe cleaner. Here are some completed caliper pictures.










Front brakes ready to reassemble. Tomorrow perhaps. Still have the rear hub and shields to clean.

Rear brake hub and parking brakes being inspected cleaned and re lubed as necessary. The pads look in excellent condition. 


A before and after rear heat shield. The brake dust sure does a number on the aluminium shield. I tried all cleaners and ended up using a mild acid ,then polished with autosol. Next a coat of clear high heat paint for future protection.

 The calipers are all assembled with the spiders and open to receive the new rotors.

This is the process of de greasing the rear hub. I put a tray underneath and use a soft brush to apply the non toxic solvent. It takes lots of brushing but the results are worth it.

Here is how you get the clips off the calipers. Squeeze them in the center and pop the right side out ot the lock.The pliars have a short piece of tubing on the end to protect from scrstches.


A thing of beauty really
Here is the correct Moly  product for the 993 brake sliders






After  I used a contact cleaner on the connections  Alex is using a silicone grease paste on the rubber seals before connection.

Major clean up time


With the help of Alex and the torches we managed to get off all of the seized nuts holding on the heat exchangers with no damage. 



Had to do some serious detailing of the transmission. This is before and you can see the completed transmission at the end.

The covers were glass beaded and clear coated.
