    Default 14LF caliper?

    I've raced for over 30 years with LD19 and LD20 calipers. Now I'm restoring my Titan Mk5 and it has 14LF on the front and something similar, but smaller on the rear.

    The 14LF Mk III's are clearly marked and have four bridge bolts, two 3/8 and two 5/16.

    The rear calipers have THREE bridge bolts, two 3/8 and one 5/16. The rears are also slightly smaller, but they all, front 14LF's and rear ???'s use a 1.89 piston and seem to take the same size pad. With a 1.89 dia piston, they aren't SP12's, are they?

    I need to buy crossover seals once I get them re-plated and I think I can just use 14LF cross over seals. Right?

    14LF on right, unknown on left.





    Notice upper caliper half is slightly smaller than the 14LF (below)

    I think they are 12SP’s. The other alternative is the 10/8H but I think that has a smaller piston. I have 14LF’s on both ends on my Mk5 Titan.

    I probably should have just asked you, Ben. You're my go to guy for Mk5 info.

    Pegasus claims the 12SP has different size piston and only two bridge bolts, but these have three. Assymetric. Strange?

    Given they're English, well anything could be true. Maybe it's a 12SP Mk something?

    Default The reverse

    Not sure of the 3 bolt version. I have a combination on my '68 Alexis MK14 with the 14LFs on the rear and the 12SPs on the front. Just rebuilt the 14s a couple of weeks ago.

    The 14s have a 4 bolt pattern while the 12s have 2 bolts. Not sure what you may have with 3 bolts.

    For some reason my car came with the larger caliper on the rear.

    12SPs in front and 14LF in the rear leaves me scratching my head. How is your brake balance?

    I'm gonna guess that it's an LF-14 that got put on a diet. What does it weigh?

    Default 14 LFs

    The 14 LF on the left (3 bolt) is Ford Cortina A, B (G.T.) through 09/66. Ford Part #'s---R.H. 3036E 2010-D & L.H. 3036E 2011-H

    The 14 LF on the right (4 bolt) show up on later Spitfires and Elans. ... and other applications.

    Also note, one is side entry the other top entry

    Both are 1.89" piston diameter and use the same kits and crossover seal.

    Really nice TRW seal kits from England are now available. Call those guys in Wisconsin.

    BTW the 12 SP is 1.69" diameter.

    Thank you John. I figured someone here would know what they are. If I'm understanding, the three bolt was only used through 1966? So it would have been obsolete when it was fitted to a 1969 racecar. Or, it was someone's idea to save a few ounces, or more likely, a cheap replacement when the original 14LF's on the rear got damaged maybe.
    Thanks for the help.

    Default 14 lf

    The 3 bolt was used, by Ford, on the Cortina, through 09/66. I would guess there was some surplus stock left that was picked up by Lotus and others, cheaply. Capman was always hunting a deal and found of "lightness". The 3 bolt are lighter than the 4 bolt, saving on weight. The 3 bolt stock did dry up as there were 61s fitted with 4 bolt front and rear in the later production numbers.

    My 61 was completed February 69 and was fitted with the 3 bolt caliper, front and 12 SP, rear. It's all about who's stock ran out when.

    Ping Andy Antipas, he can tell you what s right for a Titan Mk 5.

    Default Original FF Specification

    Something I just remembered... in the original FF specification, from the Motor Racing Stables brochure, Item #3:

    "3- By stipulating that a Formula Ford must use a standard Cortina clutch, brakes from a Ford car and Cortina steel wheels of specified rim widths (4 1/2 J at the front and 5 1/2 J at the rear)."

    Default FF

    That changed pretty quickly, along with the wet sump requirement.

    14LFs are heavy, but a great and reliable caliper for those of us that want to keep our cars original.

    The 12SP calipers are very difficult to get hold of. They were originally fitted to the very early Lotus Elan S1s and Triumph Heralds in the UK.

    Good luck in finding some.

    My Crossle 20f came with the 3 bolt 14LF at the front and until this tread did wonder where they originated from. Plus the 12SP s at the rear like a lot of early FF 1600s. Though most early FF1600s have 14 LF fitted to the rear.
