Help please. 2007 E class 211 wagon Brake fluid renew and bleed

[OneForTheRoad]

I also bleed them . I change all 4 pads and fluid in 1 hit.

The car is off for an mot and to have a scan for fault codes as well as to see if Star can raise the ride height a little. This in a couple of days time so thought I’d change the front brake pads, and give the engine oil and filter a refresh to get everything right.
For the final insult one of the caliper pins was stuck. No amount of hammering would get it out. Eventually the pin bent within the gap and needed to be cut. Even the parallel pin punch got a bend in it. I had to remove the caliper and drill through the centre of the pin with its securing head to release it. It almost got to the stage where I was looking at replacing the whole caliper.
What a fun afternoon that was. All done now, but the lesson is try not to use this motor over the winter and expose it to our levels of road salt

Trouble is previous keepers and even garages dont do preventative maintenance on things like calipers . It takes a minute to clean and regrease things like slider pins and brake pad locating pins. My 65 plate ford kuga with fsh at ford was due new rear pads .i changed them myself . The old pads hadnt any copperslip etc put on them . The caliper slide pins were dry as a bone. Little things can mean alot to someone down the line.

You're so right.
I always coat the slider pins and the pad locating pins with MB brake grease.
It's only a small detail, but can make such a difference next time.
I had a similar disaster with my wife's old E430 rear pad pins.
I couldn't knock them out.
Penetrating oil didn't help.
I ended up bending them and finished up replacing the calipers.
Not a happy moment.

People complain how much a garage charge for changing pads, but when you consider removing carrier to clean of rust, slide pins to clean and re-grease, caliper clean then refit this takes a little longer than someone at home sliding two pads out and two pads in.
Also when peoples calipers start to stick, there is a reason for this as in damp has got through a damaged dust seal and rusted/pitted piston, either replace piston and seals or replace caliper as freeing it up will only give you a little time before you have to replace/repair.
there are even companies that can repair and refurbish your calipers for you if they are horrendously expensive to replace. after all folks one day when you really need them to do there thing, you want them to work 100%.
