I have been having an issue with my left front wheel locking up long before the others. I have done all the usual stuff. Checked/replace hoses, calipers, and pads. Bled everything to a fare-thee-well. Etc., etc. I have replaced everything but the master cylinder and proportioning valve.

I was looking for a proportioning valve, when someone suggested that my suspension might be unevenly loaded. If the left front is not holding up its fair share of the weight, it could, theoretically, make the wheel lock up prematurely. (This, in spite of my fat azz being in the driver's seat.)

With that said... I probably should have the car weighed, corner by corner. Lots of race shops are equipped to do this but, unfortunately, I don't know any of them.
Anyone have any suggestions? (I have already heard the suggestion of driving up to the weigh-station scales, when they're closed. Don't really want to try that, just yet.)

How about the brake hoses?  Maybe the right front is starting to collapse and not letting an even amount of pressure go to both front wheels?

Let me make a phone call and I should have access to a set of scales. We can find corner weights, cross weights, front %, rear %, with without driver,  etc

  Hey Scott,  I would surely like to get in on that also, I haven't Scaled mine yet and really need to. Season has started AGAIN and I'm still not ready.
                     Thanks.

Charlie, the brake hoses, calipers, and pads have been replaced. Thinking about it, the car has been that way, as far back as I can remember. Nothing that I have done, has helped.
I was about to try to find a proportioning valve. It's the next - and last - logical piece to replace. If I have to, I'll steal one off of the "ghost in the machine" (aka "the project".) But I'd rather not.
The master cylinder is really not suspect, since it feeds both fronts out of one port. The proportioning valve splits it up, left to right.

Scott, sounds good. Please let me know what you find out.

You could convert your Fiero to right drive, to see if the weight change helped.  J/k.

Seriously, though, after the scales, you could test brake pressure at the caliper, for each wheel, or at least for the front wheels.  I would expect them to be the same, side to side.

That's a thought. But, just like the scales, I don't have the tools handy, to measure this.
Fieroguru quoted some really high pressure numbers. Takes better equipment than I've got. But That's probably next, if I don't just "shotgun it", and replace the proportioning valve.

Well, see what the scales show.  Maybe a trip to Champaign, IL is in your future.

Just curious, but how do you do the track stuff and the RFTH events with brakes like this?

There's a good proportioning valve on the Warrior Project car.

That's a thought. I'll message Paul, later on. Thank you. :)

Still nothing?

This will be available at the 35th.

Raydar, do the other 3 wheels lock up?

The other day, I managed to lock up the front right side. So it may just have been road conditions. Not going to worry about it too much, for now.
Car isn't drivable, just now, anyway.
