OK Gents, try this on for size. Last weekend took the Ex in for an alignment. The tech tells me the front brakes look pretty bad. I go take a look and yes they are bad. They want $1200 for new everything up front. $300 and an hour later I'm starting the job myself. New everything. Rotors, calipers, pads, seals and hoses. Reused the wheels bearings as they were fine. No real problems. Yet.
Start to bleed the brakes. Problems. Start at the rear passenger tire. Won't bleed. No matter how much I pump I can't get any pedal or any fluid or anything. Switch to the driver's rear. Same thing. Hmmm. Try the fronts. they bleed fine, get a great pedal. Start her up, pedal drops.
Pull the drums off, it's obvious the rears haven't been working at all for some time. However, I've never gotten a brake warning or rear ABS warning light. I recently pulled all the codes and came up clear as well.
So, I crack the rear lines at the backing plate to see if it will bleed out there. Nothing. No matter how much I pump, no fluid to the rear, either side. Crack the lines at the master cylinder, fluid bleeds there when I pump. Try to bleed at the RABS hyrd. module on the frame rail. Nothing. Checked the lines for crimps, they come up clean.
At this point it was 3am and I had to leave for business at 8 am the next morning, so she's still sitting on jack stands. Any ideas? Wouldn't a bad master cylinder or RABS hydr. module trip a warning light or an error code? I'm kinda' at a loss here. I don't want to just randomly replace parts without some thoughts as to the actual problem.
I know you guys have it in you. I'm talking about wisdom, not all that other stuff you also have in ya'.
