This is an '86 245 that I've owned since new. My front rotors and pads were changed over 12 years ago. The rear pads almost 17 years ago. All original calipers, Girling up front and ATE in back, and original brake lines/hoses.

However, the master cylinder and octopus are fairly new and I've had the DOT4 replaced every two years.

All pads have a lot of wear left on them and the rotors appears to be in good shape. No complaints with braking performance.

I only drive it about 1,000 mi a year.

My concern is the calipers, the pistons and seals, the lubrication. I think they're all original.

This concern arises because I recently replaced my 14" steelies with 15" alloy wheels. Now I can see the calipers. Before they were out of sight and out of mind. I notice they are very dusty with missing or cracked bleeder caps. (No apparent fluid leaks.) Should I overhaul the calipers? Or just clean them up and replace the caps. Thanks.
