Thread: Rear calipers FRC9824 FRC9825 what are they?

I should explain, the FRC9824 FRC9825 are the calipers used by the Army to convert Perenties to rear disk brakes using the original Perentie drum brake stub axles and halfshafts.

So far, for enquiries both local and international, no one can supply them or can even identify a manufacturer part number from the Land Rover part number.

Have now found on Microfiche that the rear callipers used on the Perentie 6X6 are actually early 90" front callipers (RTC4999 & RTC4998)

Looking on one UK site the brand new OEM callipers are £400.49 while the Britpart ones £36.49, that's a huge difference, but would people take the risk with Britpart callipers?

Brake parts would have to meet UK standards so even Britpart would have to be reasonable quality I'd have thought.
I'm interested in this conversion too...but I only need two not four of them!

The good thing about this conversion is that the original stub axles and halfshafts are retained making the conversion cheaper.

Unfortunately the mounting bracket AYG7308, which is still available in the Ozzie LR parts chain costs almost $180 each.

It depends on where the Britpart branded units are manufactured.

In the mid 60's I funded my student days working on a production line .... when, say, 5,000 units had been produced and labelled for the "premium" brand, another 5,000 were produced for after market... all we changed were the labels. These latter units sold for less than 25% of the premium brand in a shop, but were much the same price to the reseller from the factory door...

Bosch "equivalent" fuel injectors can be bought from the manufacturer in China for US$8-15 per unit (min quantity 200) but you pay upwards of $70-96 per unit from the parts shop....

Given the disparity in price, you could perhaps buy 1 unit of the Britpart for evaluation and then buy the rest if it passes muster...

interesting! i actually had some adapters to do this as per what the army used, they bolt to the stub flange and hold the caliper. But when i tried fitting it i couldnt find the actual rotor and caliper part numbers that was needed for it, i tried many different arrangements and nothing lined up right... i ended using the early TDI200 caliper bracket machined down to suit and a combination of calipers and rotors from a later defender.

btw i have tracings of the bracket used by the army in DWG format, it was a flat peice of plate about 16mm thick i think, easy enough to have someone cut a batch up.

According to the EMEI its the front hub (AYG7350*) and solid rotor (FRC7329) off the same model.

* AYG is a locally sourced part. In this case used in the Perentie production, whether it's the same as the civilian 110 I'm not sure.
