Had that happen on a bug I owned. Locked up then after cooled off would free up. 1 Quote Link to comment Share on other sites More sharing options...

If I had one caliper locked up or one side of the turning brake line locked, wouldn't the other wheel turn fine. Wouldn't I be able to spin one wheel when I was trying to get un stuck???? No different then me grabbing a handful of turning brake and on the gas. One wheel is driving the car and the other is locking up. This situation I have been in is without a doubt both rears locked up. In forward and in reverse. The car is not going to move I have been in two gears before in a bug I have owned many moons ago. The hockey stick broke between shifts and locked the car into 1st and 2nd. It took a ton of power and clutching to get it to move when it happened. Just like this situation I am having, But..... If we jack up the car and roll the back tires it will unlock and drive out. Which is why I am questioning the Mendi S4 1 Quote Link to comment Share on other sites More sharing options...

Not saying it is the trans, but that is how they work. 1 Quote Link to comment Share on other sites More sharing options...

Caliper is parallel to rotor? No kinked hard line or hose? Have you tried flushing out your brake lines to remove any possible debris or obstruction. All good with the fluid.

What I've found is the rear brake pads may have been too thick. Now that I've machined off 25-30 thou they float. I've been running the car on stands. Power breaking and now the pads are loose and wiggle as they never did before. Pulled th drain plug on the trans and it has some fuzzies but nothing major. Thinking this is it. Maybe praying. Mostly hoping. 3 Quote Link to comment Share on other sites More sharing options...

If f one wheel is locked up you really aren’t going anywhere from a stop either Quote Link to comment Share on other sites More sharing options...

They never did before. 3 Quote Link to comment Share on other sites More sharing options...

I never really figured out what was causing this and it seems to have gone away. Prolly not much of a help to you, but maybe the same problem, yours is just more severe.

Center of the pads where the vents run on the rotor. I think the pad thickness kept the pads rubbing more than normal. Heat built up and when I would stop, they would stick to the rotors. As new these pads were tight. The whole brake assemblies and midboard assemblies were made by grey area. I haven't reached out to them with my findings yet. Since taking some material off the pads. Making them thinner, I haven't had the issue. Hawk makes the pads. They are offered in .800 - .750 - .700 and so on in thickness. These were .800's and I took .025 off each with the mill.

Car is running great. Getting very comfortable with it and liking everything that's been done. Day 9/10 and had a few issues. Air compressor started running every 5 minutes. Found the head cracked and leaking air. Set the bags and unplugged the air controller. Same day, steering started locking up. Rack finally stopped working so parked the car. Did a good look over and found drivers rear bag perch was bent. These are original and already have a new updated hd set coming. Grants got the rack for rebuilding. Grants getting the spring perches ready. Air compressor has arrived. Waiting on some 12 point bolts to arrive to remount the steering rack. Will make getting the rack installed easier. Should of got a photo of the passenger side foot pad. It's bent away pretty good. Think @Greengois still picking his underwear out of his crack. All in all. Happy and looking forward to the next trip. 4 1 Quote Link to comment Share on other sites More sharing options...
