1972 front Dunlop calipers

[Puffdaddy#1]

Having a problem with brakes dragging ,and not retracting.I have had no previous issues,pads are like new.

The fluid does look strange,was fine last time I checked but now front resivour is clear but darkish,and the rear looks to be not clear and a light brownish.

Retracted the pads using my c clamp put the caliper back on ,pushed the pedal only inside piston moves ,buy the way only having trouble on driver's side.

What's your opinions or options,can I rebuild these originals, flush and change fluids and lines?

At the very least that stuck front wheel brake cylinder assy. needs to be removed and inspected… The piston can usually be blown out with air pressure… but be careful doing that, and wear safety glasses.

I gave up trying to rebuild the Dunlop calipers. bought these Cobalt calipers and pads from Bob Ziff at Avanti parts & restoration. They are an upgraded design while keeping the original external design. These were designed and marketed to the Jaguar XKE enthusiast. but they also work on our Avanti's. My car is not yet together enough for the road so I can't as yet speak to their performance,
