The slide pin o rings and gaiters are relatively easy to do.
Is the hydraulic piston ( bendix caliper ) that is wound back in to un adjust so you can fit new pads, free, or very stiff??
If the piston is stiff, it can be "exercised" to free it off a bit, but an overhaul is the real answer. I have not had one of these calipers apart, but it can be done.
Had to replace rear flexy brake pipes very recently so soaked nipples and unions in penetrating fluid, they came out easy thank god, unlike the front calipers ( bosch ).
The hydraulic piston boot is relatively easy to replace. Got parts from Bigg Redd, mail order.
I put a length of windscreen washer pipe on the nipples and filled with penetrating fluid and got on with the front brakes, giving time for the rears to soak. A small drill was used to clean the nipple hole of crap first. A hot air gun is handy but protect the rubbers.
With the handbake cable off the caliper lever ( no real need to remove the cable completley from the caliper, yet! ) , the handbake caliper lever can be used to "pump" the hydraulic piston out, but not too far, and then wind the piston back in, repeat till free.
Hope this helps.
I presume you will be changing the old brake fluid for new fluid.
Bigg Redd has on line tutorials that make it look sooooooo easy. The front calipers are easy, just take your time and absolute cleanliness, not done rear calipers, yet.
