Rear Brake Discs Xantia vs BX

Post by Bluey1978 »

Hi, Please excuse my ignorance in this matter, but I have a set of REAR brake discs for a 94 Xantia TD Hatchback, can anyone let me know if these will fit a BX19 RD Hatchback ( it is an 1988 ).

My Xantia is hopefully going to a new home and I intend to let the owner have these discs IF I cannot use them.

I do not hold out my hope that I can, but we all know french mechanics so it wouldn't surprise me in the least if they would fit.


Awaiting your replies.........

They're certainly superficially similar.
As you have the discs and the car, why not just offer them up to check?

For some reason the BX discs are unique. Every other model has a (very slightly) different design. AFAIR it is just barely possible to fit the Xantia rear discs to a BX (depending on which Xantia model it originates from).

The differences are the diameter and the offset. Thats also why the Xantia rear calipers are slightly different to the BX ones. But no more than a few mm's.
Calipers for both BX & Xantia are capable of taking up a few mm's of slack.

So I get in line : try it out :D

I recall this being discussed before with some people (motor factors) making the mistake of thinking the discs were identical when they aren't completely.

Coincidentally I was looking at my rear brakes this weekend and noticed that the brake discs don't run down the centre of the caliper, they were very close to the inside side of the caliper.

If the disc has the wrong offset, when things get worn the pads might become prone to dropping out of the caliper or the pistons might be out to far, that sort of thing isn't good ;)

Hi kowalski, the calipers aren't offset its caused by corrosion, plenty of advice on here. john.
