05 Aztek drum to disc conversion

Followers

March 30, 20206 yr

I am a fairly new DIYer attempting to upgrade my Aztek and have recently thought to replace the rear drum brake system with disc. Problem is, I haven’t found any conversion kits for the Aztek. This comes as no surprise because there is practically nothing for the Aztek when I’ve searched for other upgrades as well. I was wondering if anyone here knew of the best way to execute this conversion.

The best suggestion I can give is look into a comparable year Buick Rendezvous rear brake setup (I know that in at least 2005 the Rendezvous' had rear disc brakes) and since the Rendezvous and Aztec are the same vehicle (at least mechanically), that may be the best way to go.

I’ll do some research into that and see what I find, thank you.

Agreed. The Aztek and Rendezvous were sister vehicles on the same platform. You may also need to get the brake lines and other parts from the Rendezvous as well.

That’s a 10-4 good buddy. Those are interchangeable, but you have to get all the hardware! Brackets, dust plates & the master cylinder will be different so will the in-line restrictors. Then there is the obvious.
