Heres hoping that one of you chaps may be able to shead some light on an unusual problem that I have come across?
The vehicle is a 1996 Land Rover Discovery 300tdi.
To the best of my knowledge, the discs, pads, and calipers are of a standered size.
Around 12 months ago, I took the Disco over to my local garage for a full service. They reccomended that I replaced front discs & pads, plus rear pads. All of these parts were non genuine. The garage assures me that there is no way that they could have ordered parts for a Defender, (for example). Having used these chaps lots over the past few years, I have no reason to believe that they are not telling the truth.
Futher investigation would also reveal no concerns over how the parts were fitted. There is no evidance to suggest that any retaining springs may have been miss-placed.
The vehicle is currently down at RT Racing having a load of welding work done, and it was these chaps who stumbled across this problem.
It would appear that the front pads have slipped down the face of the caliper, causing a lip to form across the top of the pad. It was dam close to these lips touching, rendering the pads unable to grip on the disc, (see photo below).
The diameter of the front discs are 294mm.
The calipers are AP.
OSF caliper part number is VB4. 3247-64OC.
NSF caliper part number is VB3. 3247-64OC.
I understand that a lot of Land Rover parts are interchangable.
Do I have different calipers fitted?
Did the part company send the correct items?
Did the part manufactorer put the wrong parts in the wrong boxes?
Is the disc just a couple of mm too small? On saying that, there isn't much room for a larger disc to operate within the caliper. 3-4mm at the most.
Richard Thorpe got a new set of pads in from Land Rover today for us to look at, and judging by eye, they seem exactly the same size as the worn pads that have come off the vehicle?
TBH, this has left us all a little confused?
Any ideas chaps?
In advance, many thanks :thumbup:
