Hi, I have a seized driver's side caliper on my 1999 w202 C230K. I can see lots of corrosion on the end of the piston. I can also see that the boot is torn. I was hoping to have a go at refurbing it myself and have ordered a suitable kit with seals, boots etc. I had a go at removing the caliper a couple of nights ago, but came upon an issue which caused me to abandon until I could ask for some help here. The issue is as follows: When I went to clamp the (rubber) brake hose, the hose seemed quite firm and my clamp did not seem to compress it much. I was afraid to continue in case removing the hose from the caliper would lead to a torrent of brake fluid and the risk to emptying the master cylinder. Do I need to clamp off the brake hose? And if so, what is the best way of doing so without damaging the internals of the hose? I plan on doing a complete brake fluid change after the caliper has been replaced. All help much appreciated, Thanks.
