That depends on the situation. If you just bought the car and have no idea
of the condition of the braking system, I would replace the rear wheel
cylinders. They are very inexpensive and it is relatively important that the
car is able to stop when you want it to.
OTOH, if you replaced the rear cylinders last year or two years ago, and are
doing a routine brake inspection, I would just look them over externally.
When you upgrade any part of a hydraulic system, the oldest seals become the
weakest link. This is frequently seen when you replace a master cylinder and
then the calipers or rear cylinders start to leak. The increased efficiency
of the new master cylinder is more than the older seals can handle.
Just my 2 pence, but, Safety Fast!
