| Without doing an actual physical check yet, I am experiencing a slight clonking from the front when applying the brakes on my 1972 96 V4. Steering is fine and suspension seems good whilst travelling along,but it seems to me like the pads are moving in the callipers which were overhauled recently by the previous owner. Any heads up if anyone has experienced this.
Thanks in advance, Paul.

| If you think the pads are moving in the callipers then you need to inspect the front hubs immediately.
If you have not got the mechanical expertise then have someone experienced Look at them.
There are areas that can wear:-
The bottom pivot area, the two parts can wear allowing the parts to rattle.
The top retainer spring loaded slider can seize, the slider wear allowing for movement.
The pad contact areas can can wear so that new pads do not seat correctly.
Close up photos can help to identify the problems.
Below components for identification, a set I recently overhauled.

| I was about to start a thread with same subject since I’m having a similar clonking sound when applying brakes.
As I’ve written earlier, I failed to take the V4 to the international so I decided to take it to the annual Danish club weekend meeting, which this year was a 3-4 hours drive each way.
The car and I both survived without breakdowns, but I was rather concerned about the sound since I have heard about brake discs coming loose of the hubs.
I stopped on the way there to re-torque the wheels, but they were tight.
This summer I did "refurbish" the front calipers a bit before the inspections (MOT) using a large hammer and some penetrating oil, so this might have loosened them up a bit. However, when taking off the offside front wheel, I could’n see or feel any play. Sound seems to come from both front wheels.
Should I check my hubs? I’m considering doing a real refurb on the calipers, but finding all the required hardware seems to be a bit difficult.
Any advice?
Regards, Mads

| | You could jack up one side of the car, take the wheel off, start the engine, put the car into gear and get someone to apply the brakes, to see where the clonking is coming from? | |

| Thanks Simon, sounds like a plan. I'll see if I can get some help to do it. Or at least doing it alone, I can determine which side it's coming from, if not from both.

| I've had many 96s over the years and most have done this.
Sometimes it seemed to be only when applying the brakes between forward and reverse. Other times it was when the pads had been renewed.
In my case it was wear on the caliper pivot that caused most trouble.
Ironicall, a freshly service caliper which is running nice a free, will more likely clonk than an older one because it can move more easily.
