Truck pulls to right on brakeing

[73m819]

Swiss,s m62 pulls to the right when braking, I can lock up the right front as well as the rest of the tires, there is about 300 miles on the whole brake system, I can tighten up on the left front till the wheel is tight to turn by hand and at the same time have the right front backed off, the right front still look up and pull to the right while the left front seems to do nothing, no fluid loss, good pedal, no air in system, any ideas, I most likley will pull the left hub tomorrow

Check for a bad rubber brake line on the left side. If it swells under pressure, there is less pressure to that cylinder.

The line is brand new, about 300 mikes old, though that is one of my thoughts

Leaky wheel cylinder will cause that wheel to lock up.

The wheel cylinders are all brand new with about 300 miles though that is a thought also, do not see any signs of a leak, no loss of fluid, good peddle, if this was a old system I would know where to start looking, but EVERYTHING is NEW but the steel lines and those were flushed out. Guess it is time to pull the front hubs

There could be trash in the brake line. Are you sure they are adjusted correctly? There may also be a broken part in the brake assy. Im not familiar with an m62 but if it has abs there may be an issue there also.

This is a 1955 wrecker, adjustment is good, all the lines blown out before the new cylinders were installed, about the only thing I can think of is something is broke in the left front, we may know tomorrow or sunday

Ever found out what was the problem?

Yes, sorry everybody for not updating this thread, one of my pet peeves, members not updating what's wrong threads so others can learn the cause/fix, I will try to do better the next time.

The left hub seal DIED, greased the shoes/drum, I could have set the shoes tight, the brake still would have done NOTHING, replaced the seal/shoes, cleaned the drum, the trucks stops good now.
