1-1/2 bore=Raybestos WK104 (fits WC4511)
1-3/8 bore-Raybestos WK103 (fits WC4571)

For NAPA rebuild kits, just drop the WK. NAPA Canada retails at around $27 per kit. I can get the complete wheel cylinders out of the US for around $10 more. But there is merit to what Phil says about sleeving then only ever having to replace the rubber parts. The low Chinese supplied prices will not last forever.

Hi Lynn,

Here in Australia, ABS Part No. A725 are the rear 1-1/2" cups. I bought them off the shelf from local brake shop two years ago.

They were also listed as IBS Brake parts P725E on the package.

Cheers,

Jacques

Those aftermarket imperial cups ( typically made in places like Spain) can cause problems. They are not the same width as the originals and unless your cylinder is in pristine condition, they can weep .

Also, check your cylinder with a bore gauge, for it may be oversize . PBR used to supply oversize cups but that was decades ago .

Hi Lynn,
I know Brake Service Centre in Tauranga is no longer in business but my November 04 invoice shows
P368 Boot 4 off
P4301 Boot 4 off
They will be front and rear wheel cyls but can't remember what manufacturer.
Regards,
Terry

Hi Lynn
Ford truck 1939--48 and all blitzes use wheel cylander boots no. (p)5975 front and(P( 5976 rear PBR numbers. readily available in Aus.
PBR numbers and Lockheed numbers are often the same . PBR may use latter P , Lockheed use FC.

Hi John

PBR don't manufacture imperial sized cups any more . They sold all of the dies/moulds to a guy who apparently destroyed them or sold them off-shore. You may get lucky and find a store with some old imperial PBR stock, if you do, buy them all . My neighbour has had problems with the IBS imperial aftermarket cups made in Spain , leaking -weeping in a AT4 dodge truck , they are narrower cups than the PBR ones . We did think of using two of them in series eg 4 to each cylinder . Mike
