Hmm. Although I got a good result at the end of things, Operations Discs & Pads did not go as planned...
The intent was to replace all the pads and discs for all four wheels, as I was getting a grinding noise, apparently from the rear nearside. THis, coupled with a visual inspection of the nearside rear disc, showing rough scoring in the outer edges of the disc, suggested to me there was a problem on that disc. So, easiest first, replace the front ones, where access is easier.
Wrong.
While the caliper, caliper guide pins, and pads, came out dead easy, the caliper carrier bolts, however, remain another story. They're still there. I spent most of yesterday trying to shift the blasted things, to no avail. I tend to the opinion that they're original installations, and the amount of rust around them would seem to confirm this. So, I gave up on replacing the disc (I have to go to work tomorrow, and this wagon's my daily drive), and jusdt replaced the pads. Since I couldn't do the disc on the offside front, I went to replace the pads only on the nearside, and this is where I got a surprise.
Removing the caliper on the nearside front required a
lot of mucking about, and I found out after I'd removed the caliper just why: the screw holding the nearside brake disc in place was well bloody loose - I found this out because the disc wobbled in my hand. So, I removed screw (using only the bit from the screwdriver, it was less than finger tight!), cleaned out hole with an air duster, wire brushed the screw (which was
FIIIIIIILTHY!), cleaned the brake disc again using a brake cleaning spray, and refitted the screw in the hole, finalising the thing with my impact driver. Having then fitted the replacement brake pads, guide pins, guide pin bolts, and the caliper itself, I then spun the hub a couple of times and lo and behold, minimal grinding!
Having remounted the wheels, I took the car on a test drive (up and down my street). The test drive produced no grinding whatsoever, even under the stress of a simulated emergency stop.
So, I never even had to mess about with the rear brakes, which was a plus!
So, the spares shelf in the garage is getting filled again. Now, I have a LOT of bolts, and four spare brake discs!
And, of course, a working wagon again
