I finally got the brake master cylinder back for my 1989 Porsche 928 S4. It looks better than new ones. The company I used was White Post Restoration out of White Post, VA. This brake master cylinder was sleeved and has a life time warranty. I highly recommend using White Post Restoration. The packaging they used was very professional.
I plan on now removing the power brake booster. During the troubleshooting process the brake booster displayed symptoms of being bad. It also is very rusted. Behind the brake booster area and nearby,, I will be adding more insulation to the firewall to reduce the amount of heat passing through the firewall.
Previously I purchased a Duracell Battery for my 2017 Toyota Tundra with the 5.7L V8. The battery was a Group Size 27 :-). The downfall for the first Duracell Battery was it had a crack on the top by the cap area and leaked some fluid.
I took it back into the store and they replaced it without any problems. I now highly recommend (still recommend small businesses as well) Batteries Plus Bulbs located at Camp Bowie 5825 Camp Bowie Blvd, Fort Worth, TX 76107. I do recommend that you go online and put your e-mail in for their updates. Some times they have a flash sale to save 15%.
Anyways I found out you can still use that red terminal protectant on both the positive and negative. Your actually supposed to spray it on the post (to prevent corrosion in between the post and wire connection). So I sprayed it on the post. I sprayed it on the wires. I sprayed it in between the two wire connectors for the positive side. By the time this Duracell Battery dies, I should have the mechanical problems on my 1989 Porsche 928 S4 fixed. I plan the next battery go around to use a much larger AGM battery. That is going to require my to use longer wires.
The company that is going to rebuild my brake master cylinder said they received my part. For the power brake booster, I am going to buy a new one. Surprisingly that booster is on cars other than a Porsche 928 so the price is not ridiculous and the company makes a large amount of them.
