well ripped off the rear wheels & drums to find leaking rear wheel cylinders.. would this give the pedal somewhat a spongey feel?

Any hydraulic leak will cause a spongy feel. I thought the first roady bloke told you that they were leaking. Didn't you fix them?

nope, got distracted by other things and must have forgot about them, mainly because they werent leaking enough to make the handbrake stick.
i messaged someone ages ago to buy some (never used, sat around in shed) and they never got back to me, im gonna try bursons 2moro...

Don't buy them when they've been sitting in a shed.. Get a new pair. If you ask for them to suit a 1.6 they are about $25 each complete brand new.
The 2L ones are very expensive and only slightly different. The 1.6L ones will fit and you won't know the difference.
Cheers,
Andrew

From memory PBR numbers are;
64677551 - 3/4" 2ltr original equipment but cost mega $$$$$$
P10033 - 11/16"
P10034 - 3/4" (from cortina, identical to 64677551)
P10035 - 13/16"
all identical outer dimensions, should be able to get any of the P series for $30-$35 each
Cheers

The part numbers you need are these:
1600: P10033 These are 11/16 bore
2 litre: P10035 These are 3/4 Bore
If you order the 2 litre cylinders by this part number they arent any more expensive than the 1600 jobs.

I stand corrected - havn't sold spares for over 10 years so the memory is a little rusty... Cheers

Did you adjust the rear shoes before bolting the wheels back on?

I cant believe this topic has got 3 pages of replies ....
First thing - Clamp off the rear brake hose and then test the pedal. If it still feels the same then your problem is NOT in the rear.
Second thing - clamp off both the front hoses as well and test the pedal. If it still feels the same then your problem is not air in the lines. The master cylinder is stuffed!
Finally, before you adjust the rear brakes make sure the handbrake hasnt been adjusted from the cable. The handbrake levers inside the drums should be free against the trailing shoe. If the handbrake has been adjusted you will never get the brake pedal feeling right.
Back off all handbrake adjustment, adjust the shoes and then re-adjust the handbrake only if you need to.

If it's still low clamp the front left and feel the pedal again then the right. If it's still soft the problem is in the master cylinder.
You could have saved yourself a lot of time. This was the 7th post on this thread.
