That’s not supposed to happen (Post #280) 1/4/2012

QUICK! Name three things you didn’t expect to happen when you got home today.
Was one of them “finding a puddle of brake fluid in your driveway?”
Me neither.

This is what I came home to today.

You will remember in my last post that we had a brake rotor we thought was warped. On first inspection of it, I didn’t see anything like that but the evidence (sound and peddle surging) was there.

My son, Diet Mt. Drew, called today and asked to drive the Range Rover to lunch. He first asked, via text, if it was “safe” and “reliable” enough to drive. THE NERVE! He had to ask to drive my Range Rover because his Scion xB was in the shop. It was in the shop because he hit a curb in front of the Cleveland County Fairgrounds while traveling 40 MPH. Yes, a cell phone was involved. Yes he bent the lower “A” Frame, destroyed two rims…etc… but I digress.

In any event…he drove the Classic today. I did not expect the brake caliper to fail with him at the wheel, but apparently it did. He reported all this to his mother, the noted blogging mechanic in the family  “that he had severe braking issues” while driving her today.
Did anyone call me or notify me by text?

I’ve rebuilt that caliper at least once. So today I ordered a couple of re-manufactured brake calipers. They were half the price of new and free shipping, so I bought one for each side on the rear. No core return, so I can rebuild my old and tired ones again and have a spare….just in case Diet Mt. Drew drives to lunch again. (wink, wink)

If you remember the last major brake restore (I keep referring to these previous posts like you all are AVID readers) I swapped brake hoses and ground off all the rust (theoretically) and re-sprayed the brake calipers with some acid-etching primer. It was kind of silly because brake fluid is a paint solvent. But I felt obligated.

When I had them apart I noticed a lot of rust. Especially inside the caliper. I even took a picture of the rusty bleed screw, see below. The picture doesn’t show it very well but it was pitted with rust.

When I did that project, it was determined that I had a bad proportioning valve. I vaguely remember replacing it. But quite honestly if I hadn’t seen the picture labeled “Valve that failed” I wouldn’t have remember it.

It is likely that these old tattered calipers are past their prime. I’m a bit surprised with only 191,000 miles on them. (okay I’m not really all that surprised).

I’ll let you know how the replacements go and whether or not I’d recommend the company as a source for parts for your Range Rover.

Thanks for reading and Happy Rovering.
