My wheel cylinder is rhe shorter spring on the left. The kit came with the spring on the right. Should I return these and get a matching set?
the truck is a extended cab and single rears dlx so half ton. The spring is throwing me off. I ordered another kit and the seals are correct but spring is also long version.

 

Okay guys im new to the drum brakes. I was not sure which wheel cylinder kit to get. I accidentally ordered 1 ton 7/8inch.
the outside seals were different than the ones I had.
With trial and error in learned that once I got the original wheel cylinder off. The inside seal has 15/16 thankfully I noticed and not used the 7/8inch seals since their slightly smaller.
I ordered another set from auto zone since the outside seals matched the ones i have but they were also 7/8 inch inside seals. I only need the outside seals.
why is it so complicated to find the right part.
also I think the 7/8 springs are slightly stronger.
I ordered another set that is 15/16 hope the spring is different strength. Ill get it tomorrow

 

drum brakes can be a pain, it helps to take the old parts to the store if possible.

turn the drums if you can find a shop that still does it :-/ coupled with a new set of shoes it can make a difference.

larger bore i.d. wheel cylinders would be the right choice with a bigger i.d. master cylinder, for instance i used these 1" bore slave cylinders with the 1" fj80 master on my 4runner:
for $14 it's not worth the rebuilding hassle; the smaller bores are cheaper.

 

thank you for the response. At this point im so confused. Turns out that the truck has different wheel cylinders.
The left had a 7/8
The right had a 15/16
now im super confused since i dont know what it had originally.

the truck is a extra cab v6 and the front calipers are F18Q calipers.

now based on this info im leaning on getting the 15/16 cylinder.
would the bigger cylinder cause the rear brakes to grab first or the front would still grab first? @osv

 

that's a good question, i'd guess that factors like the bore size of the master could affect front vs. rear, and then there is that proportioning valve(?) up under the bed of the truck, mine has been wired down(wide open?) ever since i got the 4runner.
