GTR 260 kit questions
Posted: Sat Feb 13, 2010 4:13 pm
I have checked Caprisports website but some information just isn't there. I have been trying to sort out a kit to install the GT260 front brakes on my US spec 76 Capri.
Brakes: The easy part. Known as the Sierra XR4i by the UK the Merkur XR4Ti is still pretty plentiful here. Getting the calipers and the brackets are cake.
Booster: here's an example of what the US Capri have

It's got the vacuum port at the 2 o'clock position but I don't think this a larger servo. Trouble is Capris here did not come with 2 types of servos. From 70-78 they were all the same.
Master cylinder:
Does using the gt260 front brakes require the use of a proportioning valve?
My plan is to keep the V6 rear drums for now. Would the Granada booster with the larger 23.8 bore suit the task? My understanding is the rover 25mm bore is only needed if fitting rear discs. Do I need a larger proportioning valve no matter what?
Modifying hubs: As the caprisport website shows it's pretty easy to do. However, one point is not specified. how much is the wheel location lip increased? I would assume it's exactly the thickness of the rotor, but I'd like to be sure.
The trouble with doing a brake conversion like this is the shipping. The brackets themselves are inexpensive to ship, but if I had to ship a servo...Suffice it to say I'll be trying this upgrade with the stock fitted servo, even if it's not large enough by Caprisport standards.
