1975 bay 1600TP I have a clicking noise which started when applying the brakes the other day. Goes with the revs and can be heard after driving about 10 mins. Its not really a hard knock but a ticking/clicking when can be heard in the cab so feels like its travelling up the brake pedal too. I checked the front disc brakes which are fine. Checked the rear brakes and found one side needed adjusting (could nearly take the drum straight off without taking the star adjusters back). After adjusting the shoes to a nice swoosh swoosh I now have the clicking noise again but this time its while driving normally. Its constant but goes away when braking. Could it be the CVs are on their way out and the forces when braking are causing the clicks?
Sounds very possibly CVS , if you grab hold of the shaft and push it in and out it help redistribute the grease, might temporarily reduce the noise and give you a diagnosis for further investigation, it’s only a temporary fix!
@Lasty had this and it turned out to be the handbrake lever had come loose in the drum and was catching on the back of the studs. There was a very audible ticking in the cab as the sound was being transmitted along the handbrake cable
When this happened to me it was very loud and only occasionally, not once per revolution. @Aussiboris is the sound related to the wheel's revolution, or more intermittent?
Thats a good point. I noticed the brace bar of the handbrake mechanism in the drum is a little looser on one side. I think the square cutaways have worn over time.
Seems every revolution. Starts after a while so I think things need to expand first. It goes away a little if I engage the handbrake slightly while moving.
I would check the hub nut, when you're braking, or using the handbrake, the wheel is held clamped, the clicking could be an eccentric wobble, check for a loose hub nut or even loose wheel nuts, although the wheel nuts seem less likely as the brake being on makes a difference.
Handbrake lever falling off sideways can start catching on the back of the wheel studs. When it happened on mine, pulling on the handbrake while driving along changed the noise. The horseshoe clips that hold the pin through the hand brake lever when fitted incorrectly can drop off and orbit the brake shoes making noises every time it takes a bite out of the brake pad.. Mostly though CV joints are often clicky as they wear. Massage the boot trying to push grease back in to the metal cylinder part of the joint can make it quieter.
Try easing the handbrake on a few clicks as you drive along at maybe 15mph . If the clicking stops your problem is the internal lever catching the web on the drum , as you lightly tension the cable it'll take up the slack and pull the arm towards the cable entry and away from the drum webbing . Solution on mine was to shim out most of the lateral arm play with a washer ... Sent from my SM-G960F using Tapatalk
Thanks Lasty really useful info. Still trying to remove the hub nut so I can examine everything carefully.
If it's a wide 5 earlier style then the drum and hub is a single assembly. Later narrow 5 fitment, the drum is held on with lots of rust between the hub , studs and the drum and two M7 bolts that are meant to be doing the job, and an optional ridge of rust around the edge of the drum.
