Austin 1100 Handbrake shoe replacement

When do Austin 1100 handbrake shoes need to be replaced?

Brakes are one of the most important components on Austin 1100's and the handbrake is a crucial part of the braking system, working to keep your vehicle stationary and secure.

Austin 1100's have drum brakes and/or disc brakes and the handbrake shoes are typically located at the rear brakes.

For drum brakes, the handbrake uses a manual mechanism that works the brakes in a similar way to pushing your foot on the brake pedal.

Disc brakes are a little different and have a disc brake rotor and pads to stop the vehicle. In vehicles fitted with disc brakes, the handbrake shoes are utilised inside the drum (or hat) on the disc brake rotor.

Handbrake shoes are curved half-circles containing friction pads that are mounted to sit against the walls of a cylindrical metal drum. The drums attach to the wheels and rotate as the vehicle is moving.

Handbrake shoes work on a spring mechanism that keeps the shoe just far enough off the wall so the drum can spin freely whilst driving. When you park and apply the handbrake, the handbrake shoes are forced against the wall of the drum to hold the vehicle in place.

For drum brakes, the handbrake applies the brake shoes against the drum manually. For disc brakes, the drum is the centre of the disc brake rotor. The handbrake shoes are mounted on the inside of the drum (or hat) and forced against the inside of the drum wall when the handbrake is engaged.

The front brakes take on more braking load than the rear brakes. If you have drum brakes on the rear, your brake shoes (or handbrake shoes) will generally last twice as long as your front brakes. When the brake shoes do need replacing you may notice these symptoms:

• Grinding or squealing noise as you apply the brake pedal
• The brake pedal goes all the way to the floor
• Vibration through the brake pedal
• Rattle or metallic noise coming from the brakes
• The handbrake lever is not functioning as usual
• The vehicle continues to roll when the handbrake is applied

As part of replacing the brake shoes, the brake drums should also be cleaned, measured and resurfaced or replaced if required.

If your Austin 1100's handbrake was to fail, you put yourself and others in a vulnerable situation.

If you don’t replace handbrake shoes when they have reached their wear limit you do run the risk of damaging other components and if you have drum brakes on the rear you run the risk of your brakes not working when you need them.
