A front wheel drive vehicle with four wheel disc brakes is pulling to the left. Tech A says an external kink or internal restric
tion in the LF brake line will result in this condition. Tech B says to use a compression fitting to repair a section of brake line. Who is correct? Tech A Tech A Tech B Tech B Both Both Neither
A front-wheel-drive pulling to the left can result from several factors. One of them is definitely a faulty break.
A correct diagnosis linking the problem to the brakes is when there is an internal restriction and the pull is constant to one side and gets worse when the brakes are applied.
To confirm this, one would need to lift the vehicle and rotate each wheel by hand to check for excessive friction.
So the restriction may be caused by:
brake calipers that are sticky to the drum
too much brake fluid in the brake master cylinder - this prevents the caliper pistons from retracting when the brakes are released
