Today's adventures in the man cave started out really bad, as I wrote above, because I ordered the wrong set of Yellowstuffs. The worst part is that I can't blame anyone but myself and my own laziness. Rather than enduring those boring 20km to double check which calipers I have on my car, I used the VIN number and production date for reference. Bad choice... However, after an emergency trip through the blizzard (sadly, in a FWD Peugeot 407 Coupé that doesn't let you turn the ESP off when doing more than 50 km/h... and its factory ride height means you might as well put a yellow warning beacon on the roof since it acts as a plow) to buy some more tools, I started taking the calipers apart. Since I don't have compressed air at my disposal, I had to improvise to get the piston out of the caliper. The weather didn't encourage any trips to the garage, so I couldn't hook up the calipers to the car's brake lines again and "pump them out" that way, so that good old trick was out of the question. Instead, I used the following: - A bicycle hand pump - A nozzle for inflating footballs etc - A brake hose with the correct M10x1.0 thread. I'm gonna change mine to braided stainless steel hoses, so I chopped mine of with a knife. The pic explains the rest, doesnt it? Fit the brake hose on the caliper, stick the nozzle into the hose and go crazy with the pump until the piston comes crashing out...
