83 W126 300SD, "Rena 2.0" developed a horrible grinding screech at the right front wheel.
The front wheel bearings were okay on both front hubs.
You guessed it, the brake lining on the outer front right pad was AWOL and metal on metal braking ensued.
My independent mechanic let me order OP front rotors and OP semi-metallic front brake pad at his cost.
Last weekend I replaced the front rotors and the DS brake pads.
The outer piston on the PS caliper had siezed.
"Rena 2.0" had to spend the week perched on jackstands in the driveway.
Friday I received the rebuilt PS ATE caliper from my independent mechanic (also at cost...yes!!).
The caliper was complete with new bleeder, bleeder cap, brake pad pins, retaining spring and heatshield for the piston dustshields.
Today I finished the front axle brake job.
The front brake sensor harnesses were replaced with used Pick-n-Pull units from a 91 W126.
The old ones had frayed and had been poorly repaired with crimp connectors by the PO.
Of course, I cracked the PS plastic clip that holds the PS brake sensor harness to the top bracket that also secures the flexible brake line.
I planned to replace the flexible rubber brake lines with new ones I had on hand.
Unfortunately, they did not fit the bracket, the female end of the hose needs to have the 17mm hex fitting.
The new ones I had on hand had 14mm hex fittings at both ends.
I will be ordering a set of front and rear stainless steel brake lines from Deerfield Precision and install them when I do the brakes on the rear axle.
Gravity bled the brakes and switched over to DOT 5 brake fluid (Motor Medic brand from Walmart...it has a purple tint).
Bedded in the new brakes, brake pedal is nice and solid.
"Rena 2.0" is back on the road.
