Brake hoses and brakes on a 1965 GS

[jmos4]

Brian,

ah that makes sense I made a set for the 4 door when I added the 4 core (lengthened the orginal ones) thought I had to do the same

still checking on bearings got most of the small stuff painted still waiting on parts to button up the engine

doing brake and fuel lines today yeah getting a little closer

thanks agian

Rear seal is the same as regular skylark, and so is the axle, so you should be able to pull the axle out of one of your parts cars to use--just need the GS unique bearings.

I didn't know the 65 GS used the same axles and seals as the Skylarks. Now ! do! ;D
The 66-68 GS and Sportwagons used a larger diameter axle, different bearings and seals than the  regular Skylarks. So the 66-68 GS stuff is different than the 65 GS stuff. ::)

There is an alternative to using the GS 507AR bearings..... a guy on Buicks.net made up an adapter bushing to use Skylark bearings on his 67 GS. See what he did here;

Note that those dimensions are for 1967, not 1965!

Dan, also a member here, has a pair of bearings listed for $110. One with retainer, one without.

The 68-up (until they started using the 8.5) rear end is completely different--it was Buick specific.  The 64-67 rear end was a Pontiac design that Buick bought from Pontiac all those years.  They are both considered 8.2, but there are alot of significant internal differences.  The biggest differences are the big pinion bearing is alot bigger in the 68-up rear, it has 7/16" ring gear bolts instead of 3/8", and the left and right carrier bearings are different sizes in the 68-up rear end.   
   If you look at a set of upper control arms from a '64-'67 Skylark, you will notice they have "Pont" stamped in the top of them. 

[Loren At 65GS]

I will have to look for that stamping. Thanks Brian.

Brian,what # kit or wheel cylinders did you finally get from NAPA? I'm starting the rebuild process of the brake system on my 4-spd car and the kits i got are wrong.NAPA sold me kits # 422 and 423 and they are to small for the fronts for sure.1-1/16 rubbers and we need 1-1/8.Haven't taken the rears apart yet.    Thanks,Tom

Al,first off thank you for the information.Second,have you verified that these are the correct sizes for our GS cars and not what NAPA has listed for a Skylark?Reason I'm asking is i just ran into this problem with rebuild kits i got from NAPA. Front kits are not big enough as i described in this thread earlier.        Tom

Tom, for some reason, Napaonline has the wrong wheel cylinders listed for both 1965 and 1966 GS's.
If you use a 1967 GS for the search, you will find the correct wheel cylinders....same as AL listed. Specs are given as 1-1/8".   Note that the rear hose for a 67 is different than the 65-66. Other parts are the same. Al lists the correct numbers.

[Brian]

Napa online was right when I bought mine back in 2005, but I guess they have changed something since then.

If anyone is interested the rebuild kit for the front wheel cylinders are NAPA # 426 or so the parts guy tells me.I gave him the above wheel cylinder # and he cross referenced it. I'll find out tomorrow when i pick them up.Still going to buy the above parts and keep my rebuilt ones on the shelf so my kids can throw them away when I'm gone.     Tom

[65gs76limited]

Sorry it took so long to get back to this.If anyone is interested the front kits,#426 are correct.

[65gs76limited]

Getting the brakes done slowly but surely.

[65gs76limited]

Should have been from this to that.

[65GS]

looking good tom, are you using POR-15 on the backing plates?
