Thanks John. Both calipers had the wire clip so I'll replace with a PB kit as that worked before.

I am renovating the brake system on my TR4A. I have removed both brake calipers and they are different. One is a 16P and the other a 16PB. Do they need to be the same? What is the difference?

1 1/8 socket and 200lb ft with someone standing on the footbrake and the pulley is off. Thanks for everyone's advice. Hopefully only the odd drip during the RBRR rather than an oily trail.

Thanks Rob, will order correct socket to go on end of very long bar.

With the car in first gear, hand brake and foot brake applied the bolt won't budge. Any ideas?

So from the drawing I clearly have part 12 however it has a big hex on the end and it appears to be one part, see photo. I think 15 is for a starting handle which is not there. Would a big bolt be an alternative? If so I presume it extends to the crankshaft. If the possible bolt and the fan extension cone as 'welded/rusted' together will they come of together or will a woodruff prevent that? .

Hi Mikey, it will do if necessary but how do I actually get the pulley off the crank shaft?

Tr4A with a narrow belt on front, electric fan only. I have a bad oil leak from the timing cover seal that needs replacing before the RBRR. How do I get the pulley off and does it come off with the extension where the crank mounted fan would have been? Two photos show from above and below. All nuts removed from the front but bolts can't be removed until the pulley wheel is off. Levering on the timing cover is an option but I imagine its very thin and not designed for that.
