Quick question about brake calipers...

Hi guys, hope you're all enjoying your Fridays!

I have a quick question about front brake calipers...

I have a 1978 Ford F-250 2WD, 351m, with single piston calipers, and when I look on ebay to purchase some, most sellers do not list them as LEFT or RIGHT, but when I check Rock Auto, every variant lists LEFT and RIGHT.

I checked my haynes manual, and it doesn't list any difference between LEFT and RIGHT single piston calipers...

Any ideas guys?

Thanks and have a great weekend

I'm not sure on a F250, but on my 73 F100 with discs they do have different part numbers.

On Amazon...

Also, if you are getting new rear wheel cylinders, they too have left and right part numbers.

The calipers will physically fit either side, but hose and bleeders will be wrong if not correct side mounting.

As to rear wheel cylinders, I even swapped over from 1/2 ton F150 to 3/4 ton F350 RWC, same on each side. But yes calipers on front, differ right vs left.

Rear wheel cylinders won't interchange from right and left because the brake hoses will come in at different angles. swapping cylinders (if on the wrong side) will have the brake hose coming in from the wrong direction. I suppose you could bend a line to fit...

On something like that, hard to beat your local parts store. Order, check/compare when you pickup and happy. They might well be in stock also.

Thanks for the replies guys, appreciate it. I've already replaced the ***-end of the truck and thankfully eBay told me which wheel cylinder was which!

thanks again,
