This is on the SIII 88". I have not had any brake issues with this truck before. Other than adjusting about a month ago I've not done more than look at the fluid in the reservoir. No softness or pedal pumping, no pulling. Just a little squeal from time to time when its really wet out.
This morning I made roughly 50 mile trip for some shopping. parked the truck, spent a couple hours in the shops, came back to head home. When I pulled out of my parking space, the brake pedal went all the way down and there was barely any braking to be had. :eek: Pumping did nothing to improve it.
I checked the reservoir - still full. No signs of leaking at the wheels or other junctions I could get at readily. No puddles or stains on the ground where I was or back in my parking space. Checked the vacuum line to the servo - well connected and no obvious cracks or splits.
At this point I was thinking maybe the servo itself or the master cylinder had given up the ghost. Whatever it was, it looked like the Rover was getting a ride home. here's where things got weird...
I had to back up to put it back into a parking space before I called the tow. So I'm creeping back, ready to yank the parking brake handle, and the brakes worked just fine! I backed up some more - same thing. So I got bold and crept forward - brakes are now working fine. :confused:
I drove around in the parking garage for about 15 minutes with no braking problems at all. In the end I drove home the back way so I could avoid anything over 40 mph. By the time I got home I had almost forgotten that there was ever a problem.
Tomorrow I'll check the adjustment and keep an eye out for any out of round or unevenness in adjusting the shoes. If the weather is better than they say I may also have time to pull the drums and see if anything seems funky.
Has anyone seen something like this before? Any thoughts about specific problems this could be pointing me to? Unless something seems amiss, I don't want to start repairing/replacing things jsut because. On the other hand, I don't want to have the brakes fail in a more serious situation.
advice and comments appreciated as always.
