Help! Unique Brakes!

[chipper]

MGB front end/brakes/calipers:Front brakes were pulling left, locking up the left front wheel, Replaced calipers, rotors, bled they system: STILL locks up the left front. Thought of swapping front brake hoses to see if one is bad/blocked: Any other ideas on fixing THESE brakes: don't want to have to replace them with Wilwood at this time. Warm weather is here and I wnat to RIDE! Chip in Atlanta

Two possiblilities that I can think of:

Tires or wheels different from side to side somehow.

Diagonally unbalanced loading of the springs.

If you can bleed the calipers, it's not likely to be the hoses.

Chip,

I had a lot of trouble with the rusted old bleeder valves in my jag calipers. And, I had a terrible time getting the air out of my system. The solution that worked for me was to remove the right front bleeder nipple (can I use that word here , wrap it with plumber's teflon pipe thread tape, screw it back in almost to the bottom, fill a large medical syringe with brake fluid, connect it to the prepared brake nipple and push the fluid in while watching the brake fluid reservoir. When all the air bubbles stop coming up, I bleed the rest of the wheels the normal way.

It worked for me,

Does the car have a residual pressure valve? (usually up close to the master cyl.) If so, pull it out. If not, check to see if the adjustment rod on the master back to the pedal is backed off enough to release pressure in the line. Have somebody stand over the master while you work the pedal; if you get some fluid movement in the master you're probably ok. If not, back off the adjustement rod about 3 or 4 turns and check again.

Hello Chip,

Here's a longshot: it could be the front end alignment. Check the toe-in particularly.

Thanks everyone. Will check for all of the above. Wheel/tire sizes are the same. Keep ideas comming and I will report back rsults. chip

Hey Chip,

It finally registered that you replaced the calipers & rotors.

So here's another suggestion: check the right rotor. Compare its braking surface appearance to the left one. My thought is that if the left one grabs, it should have at least some slight vestiges of wear. If the right one still looks untouched, then that says the problem is in the brakes. If the right and left rotors appear equally used, then the problem is probably is somewhere outside the brakes.

Make sense?
