940 rear brake backing plate replacement
Has anyone ever replaced the protective covers (backing plates) for the rear brakes and front brakes?
Every time I put new brakes on, the surrounding parts deteriorate further and further (rust belt upstate NY). I have the brakes apart waiting for parts, but can't find any info on replacing the rear backing plates. Front brakes look simple enough, remove the hub from the spindle and replace. Not sure the rear backing plates are as easy.
Regards,
Joel

Well, here is what I found on some other site for rear wheel bearing replacement:
Wheel Bearing Replacement. [From the OEM Manual]
Type 1030, 1031, 1041 Live Rear Axles. Parts required: new bearing, new inner and outer seals, new locking ring, new brake caliper bolts
1 Remove rear wheel; brake caliper (tie it back onto the rear spring to avoid hose damage); brake disc; brake pads
2 Remove the four pressure plate bolts behind the wheel hub, forward of the brake caliper *** this should remove the clips holding the parking brake shoes, so remove the parking brake shoes as well***
3 Reinstall the brake disk on the hub, positioning the conical ends of the wheel hub nuts outwards, and use the disk to pull the drive shaft out.
4 Using a long screwdriver, remove the bearing seal. Clean the inside of the rear axle tube.
5 If your car has electronic traction control (ETC), remove the ETC toothed wheel on the shaft by pressing it off using two vee blocks
6 Using a bearing press tool or special tool 5212, remove the bearing and the locking ring.
7 Grease the new bearing by packing it thoroughly with grease and making sure the grease penetrates inner spaces.
8 Grease both inner and outer seals by packing the space between seal lips with grease.
9 Place pressure plate and outer seal in correct position on the shaft.
10 Place greased bearing and new locking ring on the shaft.
11 Press bearing and locking ring back onto the shaft until they are seated in position.
12 ETC-Equipped Cars: Using a cylindrical drift or special tool 2412, press the ETC ring back onto the shaft.
13 Install inner seal using a cylindrical drift or tool 5243.
14 Install drive shaft and pressure plate together with brake pad retaining springs. ETC cars: use care since the toothed wheel passes the inner seal.
15 Tighten pressure plate bolts to 40 Nm (30 ft-lbs) *** good luck with that, no room for a torque wrench***
16 Reinstall: brake pads; brake disk; brake caliper (using new bolts and tightening to 60Nm (44 ft-lbs); wheels.
17 Adjust handbrake cable.
