Maintenance / Master cylinder rebuild kits
« on: February 24, 2018, 12:51:04 AM »
Original GM and current aftermarket rebuild kits don't include the secondary piston. The GM secondary piston is impossible to find. Does anyone know of any vintage aftermarket kits that do include the secondary piston? Manufacturer and part number? It's for my '68 manual drum/drum coupe. Delco Moraine. 1" bore. Thanks, Joe.

Maintenance / Wagner master cylinder stop screw
« on: July 22, 2017, 08:27:20 PM »
I have a factory rebuilt Wagner master cylinder P/N R64986 coded BS for my '68 manual drum/drum car. It has the provision for a stop screw for the secondary piston but no stop screw. Are the stop screws no longer necessary or was this an oversight during the rebuild? Thanks, Joe.

Decoding/Numbers / Cowl Markings
« on: May 05, 2017, 01:03:34 PM »
While cleaning my '68 L6 Sport Coupe I noticed the large TEL marking on the cowl as well as the A13 stamp just above and to the left. The exterior colour is Teal Blue so I'm guessing that this had to be noted on the cowl. Is this often seen, and for what purpose? Is the A13 a date code? My car is an 04A. Thanks, Joe.

Maintenance / Secondary piston-master cylinder
« on: June 02, 2016, 04:38:28 PM »
I'm reluctant to reuse this secondary piston on my master cylinder rebuild because of the pitting shown in the photo. I'd appreciate any help in finding a GM NOS piston. It's for the Delco Moraine master cylinder, GM part number is 5452694 Group 4.653. Thanks, Joe.

Maintenance / Smog pipe
« on: March 28, 2015, 09:57:05 PM »
I'm gradually installing the smog equipment my '68 L6 originally came with. I don't have the smog pump yet but most everything else. My question is: could I install the pipe assembly and check valve but not the pump? Will the engine run normally? Will the engine require carb and timing adjustments? The carb and distributor are the original smog units. Thanks for any help. Joe.

I have a NOS front wheel cylinder with one of the pistons stuck. Any ideas how I can unstick it without taking the cylinder apart or causing any damage? Thanks.

« on: January 29, 2015, 09:56:45 PM »
Has anyone had any experience, good or bad, with Brake & Equipment Warehouse in Minneapolis, regarding master cylinder resleeving? Quality? Workmanship? reliability? I will have mine done soon and would appreciate any comments. Thanks, Joe

Restoration / Reveal Moulding Scuff Mark
« on: July 08, 2014, 12:44:59 PM »
My windshield lower reveal moulding has a noticable scuff mark. Is it possible to polish it out? The moulding is the GM original on my 1968 coupe. Were the originals made of stainless steel and polished or chromed? Thanks, Joe.

Maintenance / 1968 Front Drum Brakes
« on: March 25, 2014, 08:24:28 PM »
GM specifies a different part number for front brake shoes used with finned drums as opposed to those used with non-finned drums. Can anyone explain the differences in the shoes? Thanks, Joe.

General Discussion / Replacement parts - Country of Origin
« on: February 26, 2014, 07:42:12 PM »
I've been told by a couple of parts men that some aftermarket parts that come in boxes with a label stating "Made in U.S.A." are not necessarily made in the U.S.A. Does anyone have any evidence of this being the case? Once upon a time parts that could be stamped were stamped with the county of origin. Now a lot of parts are not stamped so we have to rely on the country of origin stated on the box to be correct. Any experiences, opinions? Thanks, Joe.

General Discussion / Brake Shoe "throat" size
« on: December 14, 2013, 10:09:13 PM »
Exactly what is the brake shoe "throat", and what size is it on my 1968 with manual drum brakes all around? Do the front and rear brakes have the same throat size? I've seen replacement brake shoes showing both 1" and 1 1/4" throat sizes. Thanks, Joe.
