Bigger brake cylinders

[jbone]

All you 5th wheel guys, What a difference those new bigger rear wheel brake cylinders make!! Installed them today and found out I do have rear brakes... they have 1 3/16" bores--much larger than what I took out... . Expect I might have to replace back shoes more than 100k... . in case you didn't read the post--got mine from NAPA pn#4637337... Ordered mine on-line and got them like 3 days later... ... ... ... ... ... ... R, J. B. Oo.
