Granada Spindle Brake Upgrade

Hello everyone,

I have a '66 Mustang with P/S, 4-Speed TL, Granada spindles and calipers in the front, disc in the rear with a Wilwood 15/16" MC. I would like to either put bigger brakes up front or brakes with better stopping power, without having to change spindles. I am open to suggestions, but was wondering what everyone else did given the same circumstances. I also know that the Granada setup works, but just want something that will stop the car much better. Thanks,

Tim

upgrade your pads and you will be happy with the stopping power. Granadas should stop car no problem, but the el cheapo pads really don't work that well. Check with opentracker for some good pads for granada stuff.

Thanks for the response! I took a look at the pads that Open Tracker offers... $250.00 for a set is a little pricey, but I suppose you get what you pay for.

^^^^^^ This

I bought the Porterfield R4-S pads from OpenTracker for my Granada front brakes. Much better than the prior pads I was running.

$250?? The above link shows the R4-S at $80

My fault... I looked at the racing set. Porterfield R4 Racing Compound Disc Brake Pads for Single Piston Granada Calipers - Opentracker Racing Products

That is much better!

I bought mine from Opentracker a couple of months ago when he had them on sale for $60.

Alan, how do you rate the upgraded pads as compared to the o'reilly's house brand pads? Just curious?

and to the OP: please check back and let us know your opinion on the upgraded porterfield pads.

If Iím reading your post correctly you have 4-wheel disc brakes with a 15/16 bore master cylinder? Power or manual brakes?

If manual, the MC is marginal & could be contributing to the perceived lack of stopping power.

Manual, and I was told that a 1" bore would be better fit as well. Of course that was after I did the research and was told to go 15/16" bore.

I recently put a set of Porterfield R4-S on my Granda calipers. WOW! They made a noticeable difference over the Ray Bestos pads that I had been using.

I have Porterfield R4-S shoes on my drum brake car and they stop about 20% better and last about twice as long.

15/16" had a spongy feel on my car. When I went to 1" it was much firmer solid feel.
