What a difference...

[phillpot]

Some decent pads make !


Fitted these yesterday inplace of so-and-so brand from local motor factors.

I've actually got some brakes now

Hi Mike,
Presuming there on the Taimar, what kind of callipers you've got ? There's 2 , namely 16P abd 16PB (from the top of my head)Could you be a pal and check, would be interested in changing mine, as nearing there 'end' (on a 3000S)
cheers

Invoice says 16P, is the only difference imperial or metric pipe thread? I wasn't too concerned as I was re-making all the pipes.

HTH Mike.

Not sure 'bout imperial or metric, but mine are 16PB, so....will go and have a look see

txs a lot

Mine are 16PB which I read somewhere should make them imperial - but they aren't! Strange enough, the imperial unions screw in but are loose in the threads which made me suspicious so tried metric and they fitted correctly.

The difference could be the piston dust sheild design. looking on Rimmer Triumph Website PB come in imperial and metric ?

Have researched a bit, the pads on 16PB are 4 mm deeper (along the radius of the disc) apparently EBC Ultimax DP258 (£21.14 at 'Brakes4U')are the ones to have for PB16
Not sure why Triumph made a bit of hash of it, think www.buckeyetriumphs.org/technical/technical.htm might have some answers (btw very good site, if onto brakes/suspension)

Phillpot; Thanks a lot for yr post !

Just checked back and it was Moss Europe that lists the PB as imperial.
For the record, mine are 16PB with the "B" seal and are metric (union and bleed nipple).

Hi!

Maybe then I've got the wrong pads.
I didn't change them until I bought the car,
but I was surprised that they are a little loose in
there and they are standing out of the disc a bit (see photo).
Could this be the reason?

Difficult to read, but mine should be the PBs?

I can't remember which is which, but one type has oval holes in the top of the pad and caliper the other has round holes. The earlier pad has the round holes.

This page should answer all queries about the calipers.

16PB calipers came in both imperial and metric, the difference being the metric ones (later ones) had the shanked mounting bolt.

Between 16P and 16PB, the pistons changed design along with the boot.


The metric 16PB calipers had smaller pad retaining pin holes, and the early imperial ones had larger pad retaining pin holes.

Apparently, the metric 16PB have a 10mm with 1mm pitch thread for the input pipe and bleed nipple, but the 3/8 x 24 imperial ones do fit, but can be slightly loose.

It is just possible to drill out the small holes in the caliper to the large ones, although you don't have much material left on the caliper, but ours held up with numerous trackdays, they were only replaced due to a leak elsewhere.

The later pads, with the smaller pin holes, also have a slightly larger pad surface area.
