So, I have finished up my rear suspension and brake work on my 99 Boxster.
All new:
- Struts
- springs
- coffin arms
- track arms
- long control arms
- drop links
- sway bar bushings
- new ceramic brake pads
- new rotors drilled/slotted
- SS brake hoses
- Rebuilt all C/Vs
So, all this is back together, right now the alignment is ballpark, using paint marks from old suspension. I'm sure all bolts/nuts are torqued down to the right torque setting.
The brake rotors are one of the "black coated" brands, so the black on the rotor face will wear off really quickly, but the rest of the rotor still keeps that protective coating.
Okay, so there is the set-up. Here is my issue/maybe not an issue.
Took it out for a round the block run to see if any problem popped up. I have triple checked that everything is tightened down and I didn't miss anything. This quick shakedown was to basically see if anything fell off.
Good news? Nothing fell off. Even better, all of the creaks/thuds/bumps that my old worn out rear suspension was making is GONE.
Bad news? Holy cow do I have some grinding/screeching sounds going on. On brake or off brake, not much difference. Sounds for all the world that my brake dust shields are rubbing on the rotors, but best I can tell without pulling the wheels back off is that they are not.
How likely do you think it is that this is just my pads/rotors getting to know each other? I need to go to an empty parking lot and do the whole brake bedding in process, but I kinda wanted to get my alignment done before doing that.
Anyone had experience breaking in new coated rotors?
