Found the Cause of the Noise on Left Hand Lock on the 1929 Model A Sport Coupe

There has been a recirculating grinding type noise coming from the Model A on hard left hand locks since we changed the brake back plates.

Simon and I set off on a road test to pinpoint the noise and Simon nailed it!

The noise was coming from the right hand rear wheel.

After removing the wheel and hub/drum assembly we found a couple of issues.

  1. The back plate and brake drum had been rubbing
  2. The brake shoes have a raised metal edge and this has been rubbing on the inside of the brake

The brake shoe issue was alleviated by grinding the metal edge off the brake shoes

Once this was achieved the drum was placed in the lathe and a small amount of material removed to ensure that the drum and back plate were no longer  in contact.

A final road test confirmed that the diagnosis was correct and the treatment had been a success!

Here’s some photos of the work carried out

 

Rear Brakes and Handbrake

Those who know my A will know that it had a pretty bad hydraulic brake conversion.

I’ve been gathering parts to rectify the mess for quite a while, whilst the car is at Simon’s it’s an ideal opportunity to get things sorted:

  • Swap rear backing plates for the single adjuster 46-48 units
  • Remove all hydraulic brake pipes, rework and replace as required
  • Fit Cling Automotive custom handbrake cable set up

As always Simon did a great job on everything with a small bit of help from yours truly!

Spring is around the corner

The weather is getting more spring like by the day which means those of us with limited workshop space can start working on our jalopies. I’ve spun the coupe around so that I can remove and clean the sump out. Also I can hopefully get the front axle removed and get the kingpins, brakes, dog bones  and all the other front stuff whilst leaving the car in place. But as you can see, space is a bit tight 🙂
