Firstly I swear by Douglass Motors at Wolston.

Secondly... specialist tools not really needed as long as you have a pipe wrench (for getting the stubborn old pistons out) and I managed without a brake piston rewind tool. However, the latter would be useful. The only other thin I could suggest is a brake pipe flaring kit, cuz anytime I've takkled brakes... the pipes are always rotten and I need to get new ones. But I have a kit and some pipe/unions if your stuck.

I look at it this way most parts of my rangy i will fix myself any safety related parts eg brakes,steering etc send it to a garage that way i know its done and wont fail (in theory)

I've rebuilt several calipers. All 4 on my Disco and several others including some on comp safari motors.

Cleaning the seat that the wiper seal retainer sits in helps. I also have a piece of tube that fits over the piston and use this in a press to push the retainer home. A bit OTT but means that it goes in square first time.

Also don't be worried about splitting the calipers. Just treat them like a cylinder head. Up do evenly and retighten evenly. Replace the bolts with same spec if you are worried about retorquing them.

Worth replacing pistons with stainless ones while you are there. IME the coating comes off the std pistons and then rust. The rust then leads to accelerated wear in the piston seals.

I would agree. It makes the job so much easier. But, always replace the split line seal. And maybe a little Locktite on the bolts to be sure.

Again, 100% with you on that one. I would never rebuild a caliper without replacing the pistons if they are original chrome plated ones. Any sign of pitting and they will wreck your shiny new seals the moment you install them.
