My 1930 sedan is running fine, but not stopping so well. I have adjusted all wheels and put in new linings, but it has not made me comfortable driving on hills or at speed. Help! Any suggestions. Thanks! I'm sure this is not unusual.

Can you describe how the brakes react when applying? Do they pull to one side or the other? Does the foot pedal go nearly to the floor? Can you lock up the wheels when braking hard? If we know some of the symptoms then perhaps we can offer some remedies.

Are the linings molded? or woven with brass threads interspersed with the other fabric? It is necessary to have high friction linings on those brakes. If they are right they will plant your face on the windshield if you are not braced for the stop.

Brakes feel spongy and pull a little to left. The pedal does not go all the way down. I cannot lock the brakes, even with a lot of pressure.

The linings are not woven. I have ordered woven linings from Filling Station. They won't be available for a week or so. Hopefully that will solve the problem.
Thanks!

I have the proper woven linings on my 31 coach(according to FS ), have had the braking system completely overhauled by a local classic car "specialist" to include new rods & rod ends,springs,cotter pins,etc. Each wheel was completely disassembled and reassembled,every piece was cleaned,wire wheeled,and replaced---they look FANTASTIC---with both feet on the brake pedal,givin it all this 6'/230# carpenter has,you ain't gonna get no face plant at any speed !!! My rule is to keep a really good distance between me and the vehicle in front of me !! Will it stop---yes ... will it stop as fast as more modern cars---no way Jose' !! Never have the wheels "locked up" over 15-20 mph that is for sure...only my story--not saying how it should work.

I agree that they are in no way as efficient as any modern (or even a few years later)car. I have a 32 and can and have locked them up at varying speeds, but try not to at higher speed as I don't think that's the quickest or safest way to stop, especially with the skinny tires. I am 5'6" and all of 140 lbs and I don't need to stand on the brakes to lock them. If you have the correct linings and all parts are in good condition then it leads me to believe that the "specialist" did not do a quality job.

Hi Gents,
Maybe Junk Dog would like to answer this one, but feel free anyone.
Could the woven linings also be bonded or should they be riveted. I am doing the brakes on my Model A and then I'll tackle my 29 Stovebolt's brakes as well.
Regards
Chris

Our 32 will lock all four wheels and slide to a stop....The brakes squeal like pigs but it stops....The FS redid my shoes and I did everything else so I know they work. I still leave plenty of time and space to stop though.

Hello jay32249,
If your Coach's brake system does not lock up over 15-20 MPH, does it lock up at slower speeds? Linings that have been oil soaked or otherwise contaminated will not perform as normal. If your brakes are adjusted biased toward the rear brakes, then you will lose efficiency in the front. Can you lock up the rear by applying the emergency brake? I believe that face plant is not the issue. Before anti-skid brakes came about, the driver had the option to skid or not. You may want to try to regain that option for the sake of safety.

Hi Harry, Thank you for those thoughts. I do not really know if they were ever oil soaked,but,I do know that they were cleaned repeatedly in a tub of brake cleaner. Also the axle seals were replaced with modern seals and there are currently no leaks and the linings,drums,and all parts are free of any visible oil,grease or any other contaminants.
As stated by another member,maybe the guy that did the "brake job" did not do a top notch job of it---he certainly charged me enough though!! I could have changed over to juice brakes for the $$$ he charged me---but he has passed on to the great beyond!! Thanks,Jay
