Re: IML: 69 brakes




Well, I did not change the rotors because they were ok, got the rest of the parts from calipers on line and CARQUEST, the D10 pads came from apple hydraulics (I think) in California, it seems  d10 pads and d9 pads are the same friction material shape with a slightly different backing plate. they remove the friction material  from a d9 pad and re-install it on a d10 backing plate , d9 pads are available because they came on mid-60's gm 4 piston disc brakes. the people at apple hydraulics made me up a set for I think it was about $35.00, At the time, I did this (this last winter/spring) I documented what parts and where I got them, p/n etc. in this forum as I recall. maybe we need to set up page with all this brake info, as it is an Achilles heel of this car. thanks, mike Becker

Well, where did you get your parts for the system?? I got the Durabrake repo rotors, re-built calipers from Calipers On Line and the master cylinder and power booster from Hagen's Hiway Auto Parts. The rest of the wheel cylinders and rubber brake hoses I got from Advance Auto Parts. Please let us know your sources in case we have trouble with what we have now!!

Hi all,
 
I redid the entire brake system in my 67 lebaron back in 2002,  new parts and  DOT 5 silicone, system is still good today, with no problems. just recently redid my 67 convertible brake system with new parts and dot 5, the brakes work like a brand new car. I think the key is replacing all the parts. thanks, Mike Becker

I have finished the extensive brake job on my 69 LeBaron Coupe this weekend.
I replaced all of the metal lines except the one to the PS front and the two to the master cylinder. I used two 60" lines and a 30" line to the rear axle with two couplings. All expose lines were wrapped with 20 gage galvanized steel line. I thought long and hard about how to do this protective step and this worked great. Wrap on end of the line with a little Duct tape to protect the double flair fitting. Insert that end into a cordless drill and start wrapping the wire from the other end of the tubing. Another piece of duct tape will hold the wire from spinning at the start. With an assistant to control the drill you can get a very nice looking wire wrap with a little care. A real bonus is that if you do this well you do not need to use a tubing bender since the wire wrap will stop any kinking of the tubing. 
The new Durabrake rotors and Calipersonline calipers sure look good. Shame that no one will see them. The rotors were out of true by 0.007" on the DS and 0.003" on the PS. Spec is 0.005"! It is interesting the I can turn the PS hub by hand without the wheel attached, but I cannot turn the DS hub. I checked the rotation of the hubs before the calipers were attached and both were the same and "relatively" easy so it is due to the calipers. Note that this was the case even before the calipers were attached to the brake lines.
There are 25 connections in the brake system now from rear wheel cylinder to front caliper and I have tracked down a couple which were leaking. The brake pedal is very high and very firm. I used a Valvoline brake fluid which claims to exceed DOT 3 and 4 and used just under 1 quart.
I did not and have never "bench bled" a master cylinder. I have always read that you must do this but never have and always have had great brakes.  I just connect everything and bleed away. This time I did use a simple "one man" bleeder which has a small collection bottle with a fitting which sticks into the hole in the bleeder valves. The bottle has a magnet on it so you can attach it to the car. Hook this up and pump away on the brake pedal. The final bleed was with my son pumping and me opening and closing the bleeder valves. 
A trick for actually installing the calipers is to insert a piece of flexible foam rubber between the pads after they have been inserted into the caliper bodies as you get ready to mount the calipers to the steering knuckles. The foam will hold the pads apart so that you can get them over the rotor and then can easily be removed from the top. The calipersonline calipers use two such pieces of foam to hold the pistons in their bores.      

This has been a long and expensive experience, but my car now has brakes which are probably better than they have ever been.
