Default 86 brake problems

When I apply the brakes it will pull sharply to the left but only for a second and then straighten right out I have replaced all 4 calipers all 4 rotors and all brake pads I have had all the lines bleed at a local garage all this has not helped with the pulling problem

With all the new parts I still think you have a bleed issue. Even a small amount of air will cause the symptoms your describe.

Give it another shot. Sometimes it takes a few times to work out all the air.

Did you replace the hoses? they can go weak and swell up under pressure.
Don't forget you need to cycle the abs pump during bleeding to remove any air in the pump, try a few hard stops to engage the abs and see how that goes. Otherwise i would look at the wheel alignment, check the ball joints and bushes.
My 85 pulls up straight so yours should too, keep looking and good luck.

It's the hose. Classic tell tell symptom.

The hose on the side away from the pull is swelling, delaying the application on that side. Once it catches up to the other, you get equal braking.
