'Rena 2.0' braking news - PeachParts Mercedes-Benz Forum

'Rena 2.0', my faithful 83 W126 300SD daily driver, was literally crying out for new brakes recently.
So she got new front brake rotors, front brake pads, a rebuilt PS front ATE caliper and used front brake sensor harnesses.
Horrible screeching from right front wheel
She still needed new rear brakes as well.

I had gathered most of the parts for a long planned brake upgrade for 'Desert Rose', my 78 W116 300SD.
I decided 'Desert Rose' could wait and 'Rena 2.0' was in greater need of some but not all of these parts.

This Labor Day weekend I:
1) replaced the broken PS brake sensor harness clip with one from Pick-n-Pull,
2) installed 4 new stainless steel flexible brake lines from Deerfield Precision,
3) replaced the rear Bendix calipers with more robust rebuilt ATE wagon calipers (same pads but 42mm piston vs stock 38mm)
no heatshields though with the rebuilts (the Bendix calipers did have heatshields),
4) installed rear OP rotors,
5) installed rear OP ceramic pads,
6) replaced the parking brakes with new Textar brake shoes and hardware
(the caliper bolt retention plates were an unexpected bonus - the previous rear calipers didn't have them),
7) cleaned the wheel bolt threads in the hubs with a M12 X 1.5 tap
8) installed M12 X 1.5 X 40 studs - H&R Quick-Safe Stud Conversion Kit # 2631412,
9) mounted Lorinser RS 90 16 X 8 et 22 rims, 225/50R16 tires in front 225/55R16 tires at the rear,
10) installed McGard acorn style splined lug nuts and wheel locks
11) re-bled with Motor Medic DOT 5 brake fluid
12) bedded in new rear brakes, extra hard to steer as the PS belt went AWOL on the commute home on Friday after stopping at Pick-n-Pull in Newark

The tires are old, so the next step is new tires...at least in the front as they are not legal tread depth-wise.

I think the Lorinser RS 90 rims look better on a W126 chassis than on a W116 chassis.
More photos to come...after I get the PS belt installed.
