Dia-Compe 204 QC Questions

I have recently obtained a 1986 Bridgestone T-700. This is my first road/touring bike with drop bars. It has Dia-Compe 204 QC brake levers with QR. Can anyone please help me to know how to access and operate the cable qr feature including resetting it when I'm ready to put things back together? Also, since I'm assuming I will have to expose the mechanism under the hoods, what maintenance should be done on these (almost) 30 year old lever sets as I am sure they've never been attended to.

The quick-release is effected by squeezing the brake pads together with your hand while un-hooking the transverse cable with your other hand.

Re-assembly is the reverse of this. A too-tight cable adjustment can make cable removal and re-installation more difficult.

I am just now also noticing the levers have a quick-release latch built into the lever itself, in front.
Swing the little catch to either side, and the lever can then retract more fully into the lever body, slackening the cable 8-10mm or so.
It's one of the simplist, if less-elegant designs, but works quite well.

I really dig that style of lever with my centerpull brakes. As I run the pads fairly close to the rims, that QR makes hooking/unhooking the straddle cable very nice.

Really cool bike with really great styling!

The red T-700 is one of those *someday* bikes for me.

Keep looking! I was looking for a parts bike to build up a Nishiki Road frame. That's how I stumbled upon this on Craig's list. The original owner bought it in 86 or 87, rode it a bit then garaged it for 20 + years. He did not seem to know what he had. I grabbed it so quickly. Now that I've got my camera working, here's a picture from last weekend's ride.
