Hey all,
So last Saturday I spent some good time with my 80, continuing on through sorting various items out. Finally got to the end of my [rather lengthy] list and a noise has now cropped up which has me, at least, temporarily scratching my head. Only in forward driving, not in reverse whatsoever, I get sort of a metallic “clonk” from the left rear wheel about once every rotation.
Certain that a brake shoe retaining spring had perhaps failed, I stripped down the LR brake and nothing at all was amiss behind the disc. I should mention that on the day this noise popped up, I had performed a brake fluid flush and greasing of the UJs and topping off the knuckles with moly grease, so I didn’t, in effect, “touch” the rear brakes or hub otherwise. The rig was up on a two post lift for all the work so everything was unladen during the brake flush (if that matters due to the LSPV—I was unsure if that needed to have some load on the rear axle or not, regardless, the brakes feel fine, much better than they did prior to the fluid replacement). Anyhow, all I can think is maybe just by coincidence a bearing locknut came loose or a U-J yoke cracked (haven’t gotten round to inspecting any of that lot yet).
One last idea is that the PO had the master cyl replaced (AISIN brand) and I wonder if they didn’t get the rear brakes bled well and now that I’ve done a proper flush and [re] bleed with some good DOT 4 and have the rear brakes operating well now, maybe the caliper is causing the rotor to come ever so slightly out of kilter (the noise seems to get more pronounced when the brakes are applied) and causing a contact issue.
Anyhow, figured I’d bounce this off the consortium. See if anyone else has experienced something similar.
Thanks in advance!!
Aaron
