Which vehicles will these C-Tzu rear brake shoes fit?

How do these rear shoes perform compared with other materials?

The 781PG shoes use an organic friction material formulated to balance reliable holding force with low noise and minimal drum wear. Compared with semi-metallic or ceramic compounds, organic materials generally run quieter and are gentler on brake drums, while still providing secure parking-brake engagement.

• Organic compound reduces noise during engagement
• Less abrasive to drum surfaces, prolonging drum life
• Consistent holding force under typical parking conditions

• Cross-referenced part numbers for easy verification (e.g., 781PG, S781, 111.07810)

Are these shoes easy to install for home mechanics?

The 781PG set was designed with installation convenience in mind: the shoes align with factory anchors and contact points so a standard drum brake servicing procedure applies. If you’re comfortable removing brake drums and reassembling parking brake hardware, this kit should be straightforward; otherwise, professional installation is recommended.
