There are some major errors with that guide - where do I start . . . .
OK, with the rears, you MUST disconnect the handbrake cable from the linkage on the caliper before any tampering with the actual caliper. There was no mention of cleaning any of the working or seating surfaces in the caliper. There was no mention of checking the disc for thickness or other wear issues. Then there was no warning about checking the fluid in the master cylinder, because if it had been topped up, and you then wind the piston back in, brake fluid will spew out of the master cylinder resevoir, and if un-noticed, will strip the paint from your engine bulkhead. There was no mention of what to do if the fluid level was too high.
Then he completely failed to wind the piston all the way to the stop. Then regarding the 'copper grease' comment, firstly, most copper greases are utter shyte, including all sold at halfrauds and the usual 'motorist' stores - there are better anti-seize compounds, and even plastilube is better than 99% of copper greases. He also failed to mention about applying anti-seize to the sliding ends of the pads - this is CRUCIAL. He also failed to mention applying specialist silicone grease, such as Lockheed Rubberlube to the caliper floating pin slides, nor did he mention the absolutley crucial importance of pressing the brake pedal fully, with the handbrake linkage still disconnected.
A truely shocking 'how to guide'! 'Bad info' is actually worse than no info!
