How Can I Id My Xr6t's Brakes?

[Chargin]

I was told I have FPV brakes on my T when I bought it, Im about to get the pads changed and need to know as Im going to try and supply RB74 pads. I could take a pic of the calipers through the wheel if that helps? Front calipers are black with ford and PBR logos, rears have a lucas pad with this number on the back GDB7632. Rotors are slotted. What should I order?

Sory if this is the wrong subforum, feel free to move the topic.

they could be the premium brake package, if you could take a picture that would help

You have the BA FPV standard brakes. They are called the Premium Brakes on the XRT.

The front black calipers and and the slotted rotors are the giveaway.

Factory discs have funky dual circular groove slots on both the front and rear.

Part no for front pads is 7599

Also is it necessary to always machine the discs when replacing the pads? that's what I was told by ABS, who are doing the pad change for me. Ive changed pads on most of my cars myself over the years and have never bothered to do this.. The guy said the small grooves etc left in the disc require the new pads to bed in and this uneven pressure on the disc for a time can hurt the disc. Sounds logical but is it necessary?

yes it will give the pads a nice flat surface to bed in to. I had mine machined because it had a large lip. They start 32mm thick when new and min is 30mm. my car had done 30k and after machining they were 30.5mm

But they havent even seen the discs, they said they just do it regardless.

get them to have a look, or look at it yourself, if you can see a lip on the disc, then you should get it machined

OK take a deep breath.

More often than not the discs and the pads are replaced at the same time.

The BA FPV STD (BA Premium Brake) front factory discs are $650 each, plus fitting.

Now the good news.

The factory discs are likely a lower grade OEM variant of a dba pillar vented (kangaroo paw) DBA4000. In any case they are a very good high performance disc. These are seriously well designed, powerful and lightweight braking systems.

The dba4000 is probably the highest performance strictly convention disc you can buy. It will handle and pump the most amount of heat for a disc of a particular size and mass. (With the exception of ceramic discs, which are not conventional discs and still seriously expensive.)

The good news is you can buy dba4000's that are a direct bolt on to your system. They do not have the funky dual circular slots; instead they have swept radial slots. They are significantly cheaper than the factory discs.

Now the better news.

For $550 each you can buy dba5000s which are a direct fit onto the system.

These are semi conventional in that they are a two piece design. The centre of the disc is aircraft Al alloy. The two piece design controls disc expansion and provides even higher thermal performance than the dba4000.

The alloy hat dba5000's are lighter than the dba4000's. This will reduce unsprung mass, rotating mass and yawing mass in the steering, amazing. Suspension will feel smoother and the steering feels faster. Fitted with dba5000 an already brilliantly designed and matched braking system becomes simply amazing.

Now, for the steak knives.

When its time to change the alloy hat dba5000's, you retain the alloy hat and replace only the outer disc. I think this works out about $450 per disc, I think.

You can breathe out now.
