Mike
Thanks alot for that,going to do it this morning.
I dont suppose you have anything similar for the clutch adjustment.
I dont think I need to adjust the clutch,but I would like to check it.
Thanks again STEVE |

Here's a past post from Ric Rainbolt that I saved. It had enough detail in it that my mechanic was finally able to get the parking brake to work properly on my 308QV, after living without it for more than 5 years!
=========================================
OK, the 308 handbrake should hold an incline. That much is certain. If your
parking brake is ineffective, it can be corrected, but it may take a little
work to get there.
If starting from an unknown state, I would do the following:
1) Jack the car up and place it on jack stands.
2) Remove both rear wheels and release the parking brake.
3) On US-spec cars and some others, you have to remove a flat metal
underpanel to gain complete access to the parking brake cable. This panel
is held on by four 10mm bolts.
4) Find the cable that runs between the calipers. We'll call this cable
"A". It should route through low friction "eyes" (or cable guides on early
308's), mounted on each side of the car, on it's way to the calipers. The
eyes are either nylon or brass, depending on production at the time (or in
some cars, a simple metal tube). Refer to the parts book if uncertain.
5) Note that in the middle of the undercarriage, cable A runs through a
two-wheeled lever mechanism. It's quite common for the cable to jump off a
wheel and/or become severely frayed at this point. Clean this assembly
VERY thoroughly and lubricate with a cable lube or synthetic grease. I
usually remove the assembly so I can check the operation of the wheels.
6) Locate the buckle on cable A. It should be between the two-wheeled
lever and the right side caliper. Two open end wrenches are required to
operate the buckle (10mm?? I forget). Loosen the stop nut and the cable
adjustment is made by turning the long part of the buckle.
7) At this point, loosen the buckle until it begins to "slack up". That
is, until the caliper levers quit pulling, but not so much that the cable
falls off the calipers!
8) Inspect the condition of all four rear brake pads. If necessary, remove
the pads from the calipers. You'll get the best parking brake effect from a
new set of pads. Also, make sure the rotors are not warped.
9) With the pads installed in the calipers, it is necessary to set the
take-up adjustment within the caliper. This is accomplished by removing the
two covers over the adjusting ports. On the outside of the caliper,
normally, there is a plastic cap covering an adjuster. On the inside,
there is a cap head plug, just under the parking brake lever along with a
copper gasket. If it's the original ATE plug, it can be a ••••• to get
out. What I've done to get the inner cap off is actually use a punch to
"drift" the cap in the counterclockwise direction. I use a stainless steel
cap to replace it when done. If a significant amount of fluid is released
when the inner cap is removed, the calipers need to be rebuilt.
10) The outer adjustment is kind of tricky. You must loosen the locking nut
(12 or 13mm, I think) to turn the adjustment (4mm hex wrench). Place a
.004 inch (0.1mm) feeler gauge between the pad and the rotor and adjust the
take-up until the feeler just slips out. It should not drag significantly.
Check that the feeler feels about the same at the top and bottom of the
pad area. If its drastically different, either the pads are tapered, the
rotor is warped, or the caliper is not true.
11) Once the outer pad spacing is set, tighten the locking nut. The problem
here, however, is that tightening the locking nut has the effect of
altering the adjustment. You have to play with it a little bit to figure
out what's going on. After a bit you'll develop a feel for it and you
should be able to lock it right at the right point (.004 inch clearance).
After everything is tight, double check with the feeler.
12) The inner adjustment is easier because there is only an allen head
adjuster (up inside the hole that the cap plug covered, 4mm I think).
Using this adjuster, set the inner pad to the same spacing as the outer
(again, .004 inch). If the adjuster feels "crusty", shoot some WD40 up in
there and turn it back and forth to break loose any corrosion or dried
lubricant.
13) After setting the adjustment, replace the inner cap and copper gasket.
14) Tighten the buckle on Cable A until the levers on the caliper *just
begin to move*. Any more than this can cause the brake pads to drag,
causing premature pad and/or rotor failure (not to mention stinky smoke!).
If in doubt, check the pad clearance afterwards and re-adjust.
15) Check the lever "feel" in the car. It should only click 3-4 times
before becoming fully firm. If not, have someone help you while you
observe the 2-wheeled lever under the car. The 2-wheeled lever should
begin to pivot just as the parking brake handle is pulled. If not, there's
excess slack in the cable that runs from the handle to the lever. The
slack can be adjusted in the cockpit by opening the zipper on the leather
shroud. Looking in with a flashlight, to the right side (passenger side on
US cars) of the lever there's a nut that can be turned to adjust cable
slack.
16) Reassemble the car (underpanel, wheels, etc.).
Whew. That's all. I know it sounds like a lot, but once you figure it out,
it's all fairly easy work. :-)
Regards,
Ric Rainbolt |

How do I go about adjusting the handbrake on my 308QV.
I have checked the archives and cannot find any
reference to this.
Thanks. Steve |
