You should be able to line up the screw and the tap to verify the pitch. These threads should line up perfectly. post a picture if in doubt.

This post suggests the pitch is actually 1.5mm (I can check later on today to be sure, my tap/die kit has a pitch gauge): post911142

Have you tapped all 4 holes already? If so, I am unsure these holes can just safely be re-tapped again. This is a braking system, safety has to come first...

 

Thanks for the reply. No, just one hole done. My mistake....I do have the 1.5 pitch (although I keep saying I have 1.25). Maybe I'll try one of the other bolts and make sure the hole is free of shavings , etc. Will keep you guys posted.

Another question I meant to ask was do you know the proper torque for the brake lines at the Brembo calipers so that the crush washers seat properly?


Thanks,


Rob

 

Did you run the tap all the way in. Depending on the individual tap the lead in taper can account for a quite a bit of the length.
Run it all the way in until you can't go any more, then back out.

 

 

 

Hi,
Which rotors did you use?
I have the 2004 xkr model with the red brembo brakes but not sure what rotors to put for the rear...
Thanks.

 

I ordered a set from brakeperformance.com and I made sure to select the XKR100/Silverstone option in order to get the correct size for the Brembo's. My car is a 2002, but I believe the Brembo equipped cars all have the same sized rotors.

 

Apologies for reviving an old thread. I just bought a 2001 XJR, and I'm planning on putting these Brembo calipers on. I am confident in the swap working. I just wanted to confirm that without spacers for the wheels, I would need to upgrade my OEM asteroids to bigger wheels. I am fine running spacers as long as it's nothing more than maybe 13mm or so on the stock rims, as I quite like them.

 

You can comfortably run 25mm + spacers with stock 1 piece wheels.

 

Hi
My 2000 XJR is under some.restauration and I decide to install also the Brembo calipers at least in front if I found for sale in Europe. I see that the calilers for S type R and XJR after 2003 are more cheaper than the calipers made.for XKR till 2006 and XJR made till 2003 and also rare.
also involve more.modifications.
Will se first to find the parts Hi
My 2000 XJR is being restored and I have decided to install Brembo calipers at least in the front if I can find them for sale in Europe. I see that post 2003 S type R and XJR calipers are cheaper than pre 2006 XKR and pre 2003 XJR calipers and also rare. Their installation involves even more changes.
I use the Asteroid rims so I need spacer. I use at the back 10mm so in the front i will put 15mm if this is enough.

First to find the parts.

s-type r calipers are terrible

the f50s in the x100 and x308 aren’t that good either

 

In this case what is best to install? some suggestions?

 

I'd have to disagree if we are comparing them to the stock XJR brakes, but, yes in general, there are better, more modern calipers. However, they are quite a bit more expensive. So bang for buck value is there for the STR calipers. The S-type R calipers, while different in mounting, are fairly easy to adapt to our X308 XJR. I am lucky enough to have good welding and metal fabrication skills from working on off-road baja trucks/buggies. I have yet to do the modification but from what I can see it's quite simple to do properly and safely.

 

I search a lot on the internet for some answares but without luck.
What is the stoping distance from 100km or miles to 0?
What is the diferance in meters between R1 brakes and standard?
sime say theat Brembo F50 calipers are identical to Brembo R1 brake. Is this true?
Thanks

 

In my head, this is a tire test, not a test of the brakes proper.

Normally, "any" car should be able to stop from its maximum speed to zero at the maximum adhesion of the stock tires on a dry surface ONE TIME with its original braking system. It then needs to be followed by an extensive period of cooling. Big brakes come in when you want to do that more often than the time it takes for the stock/lesser system to cool off, like on a track or down a mountain road.

IOW, everything else being the same, I would not expect a difference in stopping distance between the stock single-piston system and the Brembo 4-piston calipers when cold.

 

Maybe you're right, but I still think there is a difference between these two braking systems, I don't think the Brembo braking system was installed just by design, there must be a difference in performance between them. I would like to know what caliper version exists for my car without too many modifications. As I said above, someone suggested that Brembo F50 would be a solution for the X308, but I have not seen anyone installing these calipers on the car.

 

f50 indicates piston diameter. the r1 caliper and rotors are the same on 100 and 308. 103 and later xkr got r1 brakes standard

you just tap the unthreaded holes on stock knuckles and you’re done

 

thanks, I thought the f50 was the caliper model. I saw what the Brembo caliper mounting procedure is, the big problem is to find them at a reasonable price. The calipers used on the S type R and XJR X350 are much easier to find but a bit more complicated to mount,
