    Anyone who is doing brake maintenance for first time this is a pretty good little visual guide to what to look for.

    There's some erroneous, even fallacious info being given out in that article. "Mineral based brake fluid"....."moisture is absorbed through steel lines and rubber hoses". Where does this writer get his info? Most brake fluids today are glycol based! Only Citroen, some Mercedes and Rolls/ Bentley products used mineral based LHM for braking systems, and mineral fluid does NOT absorb water as it is an oil. Moisture is absorbed through the breather, or vent in the filler cap of the master cylinder on our older cars. Newer cars have a rubber bladder on the master cylinder reservoir cap to allow for pressure changes without allowing the ambient humidity of the air to come in direct contact with the brake fluid. You do not need new drums as long as they can be turned and still be within specs, in the case of Hudson, up to .060" over, Paul Schuster said up to about .100" over since they were pretty thick to begin with. That article is not useful to a neophyte doing his first brake job. It seems to me to be balderdash intended to be filler material. Kenneth

    I second what Ken says. The best reference for Hudson brakes is the Hudson workshop manual for your particular model.

    Yeah I take the writeup part with a grain of salt. As I stated its a pretty good visual guide i.e. the pictures.

    Yes moisture is absorbed. Making sure you check and change the fluid is a good suggestion.

    And of course what Hudson owner is replacing the drums?? you know of any sources for new Hudson drums???

    My 53 Hornet has 4 wheel drum brakes and can stop just as quick as any new car with disc, even at 80 MPH. Ken was riding with me once and a car ran a red light and crossed in front of us and I stopped, and Ken asked if I had disc brakes, and the answer was no. If you follow my tech tip in my books, you will have perfect brakes. You can not just replace the shoes and expect to have good brakes. I use dot 5, and change the fluid every 3 years, and have 139,000 miles on fluid system and have never changed master cylinder or wheel cylinders. I drive across this country every year, Hudson club members know this, and get 70,000 on a set of shoes and am ready to change them again. Walt.

    Hi Walt, Could you tell us where your book is available or a similar source for drum brake servicing that would appropriate for Hudsons? I am in the process of getting a car on the road, and have done the basics including cylinder rebuilds, new fluid and an intial shoe adjustment. Shoes and drums were within sevice limits, but I wouldn't mind doing a another complete once over to insure maximum braking. Perhaps I overlooked drum/shoe glazing? I am a 50 Commodore Neophyte.:)

    I bought Walt's books several years ago and have used them many times. Great info and easy to understand. Richie.

    I have both of Walts tech books. There is a wealth of information and tips making these books a desireable reference to have. The information is easy reading and easy to understand. Well worth the price for these two books.

    Have a good day.

    P.S. If there were a third tech book by Walt I would buy it.

    Thanks everyone for your input. I'm officially in my "getting ready to get ready mode!" Spring is coming!
