S2 Rear brake cylinders and braided hoses

[Peter M]

When servicing the brakes last year I noticed the rear cylinder was weeping oil. I am going to replace the clinders on both sides, and at the same time look at replacing the brake hoses.

I have seen braided hose kits on ebay for the TVR S-Series, Goodridge Part No STV0910-5. Has anyone used these kits, do they fit, and is the quality ok ?

Also, does anyone know if the rear brake cylinders are standard sierra parts that I can get from the local motor factors, and what is the piston diameter?

Thank you
Pete

I bought one of the Goodridge kits for my S3 and although the quality is fine it didn't fit. The hoses in the kit have all metric unions, the rear hose on my car has imperial unions and I think I've seen mention on here of one or two others who've found the same.

The wheel cylinders are standard Sierra, don't know what the piston diameter is.

peter mine are standard sierra 2.0 ltr bore size 22.2 mm amd the cylinders are imperial thread

[Peter M]

Thank you for the tips. I'll make sure the connections are imperial before buying any hoses.

Careful now. It is just the rear flex hoses, chassis to trailing arms, that are imperial size on mine. Front hoses are metric as are calipers and rear cylinders.

Same here , I did mine last friday, Brake pipe from flexi rear hose to Slave cylinder has a Female (3/16 I think)Imperial on the Flexi end and a 10mm metric male into the slave cylinder

Mine are all metric, so for me it was:

Buy Goodridge Kit.

Fit.

And what was the result? I ask because braided hoses will expand less than non-braided but that only means that pedal travel is less for a given braking force. Which, in turn, can lead to the brakes lacking feel.

Just been on the phone the the local motor factors. They cannot cross reference the Lucas part number from the S parts guide (Lucas 64677523). They stock Brake Engineering parts. Cross referencing to a 2.0L Sierra with a 22.2mm piston, the only match was to a 2.0L Sierra Estate with 22.2mm piston, the saloon has 20.6mm pistons.

So my best guess so far is Brake Engineering WC4976 for 2.0L Sierra Estate. Not sure if this is 100% correct, may have to take the old cylinder down to them.

Oh yes, and the princely sum of £7.23 +vat

When I bought my S3c last year one of the wheel cylinders was leaking so I changed them both, one was 22mm and the other was 17mm the only ones my local factor had in stock was 17mm ones, so I got a pair of those fitted them and have not had any problems so far!!
What the implications of this is I do not know I just thought I would chip in.

Hi. I've just sourced some rear brake hoses for my S3C, which is a 1991 but built at the end of 1990. Autostores in Malvern tracked them down as 3/8" male UNF fitting both ends 250mm long which corresponds to TRW part no. PHC164 as fitted to Talbot Sumbeam 1000's 1978-80 & 1600's 1978-83! I've fitted one so far! Hope this helps fellow S 'mechanics'! Also for note the clutch kit is a 2.8 Capri item Borg & Beck HK8889. Cheers Mark

The T piece brake pipe junction attached to the frame is indeed 3/8" UNF on my S2. The rear pipes and hoses have also 3/8" UNF fittings, except the outer ones (going to the cylinders) which end in a M10 x 1.0 mm fitting. All fittings on the cylinders are M10 x 1.0 mm.
