Disc Brake Upgrade Reference Thread

[Justins76]

I am getting all the parts together and I have 2 questions for you CaptFab.

1. I'm using the 6 lug rotors, same p/n as you posted. Is there a dust cap available? Everywhere I go says n/a.

2. Is the fitting on the 88+ brake hoses the same as the old inverted flair on the hard line or are they metric bubble requiring an adapter?

Thanks!

Well I haven't had to try and find one since I started with a donor '94 1500 that had all the small parts. It would seem like you should be able to find a dust cap for a '88-'98 pickup. I wonder if the '71-'87 dust caps would work. I'll see if I can find something out tomorrow.

I'm pretty sure they are the metric bubble flare. I can verify that tomorrow as well as provide a part number for a metric to inverted flare adapter.

OK I have an update.

The dust caps for the '73-'87 C10 5 lug rotors will fit the '88-'98 6 lug rotors. Also the '88-'98 5 lug rotors use the same size dust cap. Those should be easy enough to find.

Regarding the front brake hoses. I checked one that I have from my '94 C1500 donor and to my surprise they are standard 3/16" inverted flare.

Thanks. Just goes to show its a gamble whether GM used metric or US in the 80-90s.
