99 Dodge Grand Caravan

Rt brake locks up occasionally. After brake cools, it may not occur for another 2-3 trips, but frequency seems to be getting shorter.



I have replaced brake caliper three times, brake hose, wheel bearing and am about to replace brake master cylinder.



Anything else to try?



Can ABS cause this problem?

Finally replaced the master cylinder and that has worked so far.

Considering the cost I hope it does the job.
