Help with brake parts.

[desert-rat]

So I have disk brakes from a '71 on my '69 GMC. When I'm buying parts like the booster, master cylinder, brake lines, would I just order parts for a '71?? Thanks.

Yes. The parts you mentioned will have to be for a 71 (or 72). The steel brake lines on the frame come out in a different spot, where attached to the calipers vs. where they were for drum brakes...

If this conversion has already been done by someone else, there's a chance they may have done it a little differently...beware. You might post pictures of your calipers, hoses, and such before you buy any parts to make sure...

I got the disk brakes, upper/lower control arms, spindles, and steering linkages from my buddies '71 or '72 donor truck. So right now there is no brake lines. I need all new everything brake related otherwise. Seems easy enough. Just order brake related parts for 71 or 72.

also note that some reuse the original 1/4" front lines for the disk brakes - which still works - but factory for the disk front brakes is 3/16" lines.

Thanks for that info. I'll definitely note that.

You might see if you can get the brake line mounting tabs so you can route the new lines in the factory location.
