Re: Mechanical Brakes
Many of the "early" hydraulic brake systems were very difficult to maintain because "early" synthetic materials would wear quickly and could not prevent both internal fluid leaks and external fluid leaks.
In quite a few cases years ago, after a vehicle was unattended for some time, drivers would take off and later experience the brake pedal going all the way to the floor board with absolutely "NO" brakes because of leaked fluid. Many had to perform a hydraulic brake synthetic material restoration every month or so, depending on age of car and amounts of vehicle usage. On the other hand, many did not maintain Model A mechanical brakes. FWIW as it pertains to Life Safety, "today", with our modern faster traffic, texting & cell phones, non- functional Model A brakes and horizontal rides go together ...... i.e., horizontal rides in either an ambulance or a hearse. |

Re: Mechanical Brakes
If you don't have that dual master cylinder and linkage set up exactly as designed, you may not "still have brakes in the event of a cut hose"! Have you verified that you can still stop by opening a bleeder screw on one end of the car, holding the pedal and have someone try to turn a wheel on the other end, then reversing the procedure? You may be surprised!

Re: Mechanical Brakes
Just spent a bucket load on mechanical brake bits, so I hope they work.

Re: Mechanical Brakes
What other advantage is there for fitting hydraulic brakes then? The Model A has very little grip through its tyres and mechanical brakes can be made to lock the wheels without much effort. They do, however, suit the way the car needs to be driven. I think you are just backing up my original point, well set up mechanical brakes stop the car efficiently, hydraulic brakes can do no more and are, in fact, more likely yo cause a skid.

All that said, I think the dodgey brakes, steering and suspension (compared with a modern car) are all part of the reason we enjoy driving our Model As.

Re: Mechanical Brakes
My mechanicals were completely restored from backing plates out.. every inch.. rods bushings etc. etc. etc.
I have great mechanical brakes... few people have the knowledge, skill and patience to do it right. Our club master mechanic did it RIGHT ! I tour Eastern Ky, TN, W VA. Very hilly.. went with cast iron drums... a must going down those steep winding grades!. No more fade. |

Re: Mechanical Brakes
I'm restoring a VERY EARLY 1928 sport coupe. Can't find any info on the four wheel braking system. Emergency brake and foot brake work as one system. I have some parts missing and have found zero info, diagrams or pics anywhere. Bought ($$$)all the books that claim everything you need to know to restore the A. Nothing applies to the EARLY 28. Any help? Thanks, Harold.

Re: Mechanical Brakes
I have driven 1930 hydraulic brakes on a Chrysler, wouldn't want it behind the A in a panic stop

Re: Mechanical Brakes
I've converted 2 cars back to mechanical brakes. The best thing you can do for mechanicals is USE THE NEW CAST IRON DRUMS. Work great, don't fade.

Re: Mechanical Brakes
My 2 cents worth. If the whole system is restored correctly, all the worn parts are gone, and the brakes are adjusted by the book, mechanical brakes are great. I recommend getting cast iron drums. You will notice a big improvement, especially braking on a longer hill.

Re: Mechanical Brakes
Good to hear this opinion as I'm considering doing the same to my 31' pick up. Thanks

Re: Mechanical Brakes
As with any type of brakes it is best to anticipate your stop!
