Big weekend-o-work complete!
Howdy howdy!!
Two weekends ago I completed some very long overdue work on my 99 XK8 convertible:
1) Replaced my recovery tank- SNG Barratt,- sensor stuck at the bottom, leaking around the sensor - low coolant warning gone
2) Passenger side washer jet replaced - SNG Barratt- accident took it out, now working
3) Passenger side fog light replaced - SNG Barratt- same accident took that out as well, now working
4) Passenger side leaper replaced - SNG Barratt - Green center popped off a few weeks ago
5) Front brakes and rotors replaced - Rock Auto - shuddering while braking remedied.
Total cost for all parts and shipping right around $850.00
For the brakes, they had been shuddering since I bought the vehicle 4 years ago (yikes!) I knew they were questionable for the last 50,000 miles, (WHAT!?!) but stopping was never an issue. High pedal, stop on a dime.
When I took out the pads, on the passenger side (U.S.), one pad had only 1/32" of pad left, and the outboard pad had 1/16" left. Yes, they would have been metal to metal coming up very shortly, but from driving, you would have never known they were that close. The driver side pads had a good 1/4" (.25) left, which I found to be quite odd. Now, the reason this one pad was so low, is because the caliper piston had come out so far that it almost completely unseated the pistons dust seal. It was out approximately 1/2" (0.5). The piston being out that far caused it to be at a slight angle and was the source of the shuddering (it was trying to completely come out of the caliper.)
I tried my hardest to push that piston back in, but a C-clamp would not work, a bar clamp would not work, I ran to the auto-parts store and bought the caliper pressing tool, that didn't work either. The piston was about 3/8" from flush and I was convinced I there were new calipers in my future. Then out of the corner of my eye, there it was, the solution...my bench vise. I clamped the caliper and slowly using all my body weight and an old "rounded" flat screwdriver, I pushed that piston back in and worked the dust seal back into place. Once I got the piston moving, and it was tough, the inner seal passed an inner lip and it went in smoothly.
200 miles later and there are no leaks from the caliper and the shuddering is gone...
