CLEAN AND INSPECT
Wash all brake hardware in clean denatured alcohol. Clean adjusting screw (16) threads with a wire brush. Inspect threads of adjusting screw (16) for smooth rotation over full length. If any parts are of doubtful strength or quality due to discoloration from heat, over-stress, or are worn, the parts should be replaced.

INSTALLATION

  1. Apply brake lubricant P/N XXXXXXX or equivalent to the adjusting screw (4) threads, inside diameter of socket (3) and socket face.
    • Adequate lubrication is achieved when a continuous bead of lubricant is at open end of pivot nut (5) and socket (3) when threads are fully engaged.
  1. Install parking brake lever (19) on secondary shoe (12) with pin (18) and retaining ring (17). For additional information on brake spring removal and installation see Fundamentals and Basics. See: Fundamentals and Basics
  2. Install adjusting screw assembly and adjusting screw spring (13).
  3. Install shoe and lining assemblies (11 and 12) after attaching parking brake cable.
  4. Install parking brake strut (9) and strut spring (10) by spreading shoes (11 and 12) apart. To be properly positioned:
    • The end without the strut spring (10) should engage the parking brake lever (19) and secondary shoe and lining (12).
    • The end with the strut spring (10) should engage the primary shoe and lining (11).

NOTE: In the next step, bearing sleeve (4) must be installed between the secondary shoe and lining (12) and the actuator lever (7).

  1. Install bearing sleeve (4), actuator lever (7) and lever return spring (8).
  2. Install hold-down pins (5) and hold-down springs (3).

John......

 

I am only trying to change brake pads and this seems a lot of work. I only have this car, so if I destroy, by accident, the boot or some other part (keep in mind, I don't think these brakes were ever changed so I am playing in dangerous territory and want to get to changing this at EASIEST POSSIBLE means.

 

it seems like a lot of work to just change the pads

front brakes.....

 

and John, thanx you for the info you shared. It's just that I am NOT replacing every part of the brakes.....just the FRONT SHOES/PADS there are two for each side.

 

I just want the EASIEST/SHORTEST way, (without risking damages to parts,, such as the boots, or brake lines etc) replacing the pads.

 

I think the info and photo's show a COMPLETE brake job.

 

can you explain and show me the easiest way to take out old pads and replace new.

 

 

thanx you kindly,

 

XXXXXXX XXXX

 

btw.....either way, you get great comments in the feedback and the $9.00 for helping, even if it is of no help to me.

 

if something goes wrong and i break a boot or something I have NO CAR to go and get parts, nor money......so I desperately need your help.
