Avanti front wheel cyls.

Here is a picture I took after install. You only need one bleeder. Save the extra for posterity.

Can I utilize my existing steel jumper lines with these Sumatomo calipers???

I bought new stainless, however, original should work just as well.

[StudeRich]

Use New Studebaker Vendor Crossover Lines or the Old ones if good, they are not Metric and Fit, also the Input Lines.

Just be sure to Center the Caliper "Bridge" on the Rotor with the proper shims and keep them even Front to Rear.

The mistake many people make that have never worked on these, is to remove Both Large Bolts from the Bridge to the Adapter "L" Bracket, at the Same time and let all the Shims fall in a pile. .

[Hawklover]

So Rich here is a pseudo stupid question: Why in the world would I have to worry about shims and centering the caliper "Bridge" over the rotor, if I do not remove the Caliper "Bridge"??? All I will potentially do (if exsisting units are not leak free) is remove the four calipers fit new pads and bleed the brake lines????

[Dwight FitzSimons]

Perhaps a definition or two is in order.

"Caliper" refers to the big hunk of iron that is shaped like a "U." (Think of a measuring device used to measure the outside diameter or thickness of something; That is also called a caliper.) We also often use the term caliper to refer to the "loaded" caliper, meaning that big hunk of iron is loaded with the two cylinders & pads.

There are two cylinders bolted to the caliper. Each has a piston in it. But a cylinder is not a caliper.

I believe that all Rich is saying is that if you do remove the caliper do it one bolt at a time and be careful to note the shims between the caliper and the spindle. The two bolts won't necessarily have the same thickness shims. Those shims are used to center the caliper on the rotor. These aren't floating calipers like today's cars, so they must be centered per the shop manual.

Dwight I hear you!..........two years ago at my buds shop I had his tech remove the two front rotors to pack the wheel bearings inner and outer, I cautioned that the shims MUST be kept under each bolt, somehow one bolt dropped to the floor, fortunately I was standing next to the lift and saw where those shims fell to, picked them off the floor and put them under that bolt..........thankfully no other issues!

[Hawklover]

Final question............can I utilize the standard Studebaker jumper pipes with the Sumatomo cylinders?...............do not know if they will take ones that are metric???

[64studeavanti]

As has been stated a few times in this thread, the fittings on the Sumitomo are SAE, not metric. Therefore, standard brake lines fit.

Thanks Henry, my memory is not what it once was, in fact my entire body is not what it once was!!!
