Front Brake Cylinder Question

[Robert.Long@CSDInc.com]

Hello,

Do the numbers on the front brake cylinders mean anything?  Mine don't match
and
I'm wondering if I need to worry about it or not?  Here's what I have:

Drivers outside cylinder       - 52 and HP 83 and 2 1/8
Drivers inside cylinder         - 43 and HP 53  and 2 1/8
Passenger outside cylinder - 43 and HP 63 and 2 1/8
Passenger inside cylinder   - 43 and HP 73 and 2 1/8

Thanks,

Robert
