Hafod Posted June 12, 2022 Share Posted June 12, 2022 I would say less than 0.5 of a thread, just the smallest of gaps but looks to have sealed OK after a couple of days driving, will look for a couple of longer unions and then cut of the flared end off the brake pipe and remake, luckily the pipes are a little too long so no need to make all new pipes. Biggest pain is re bleeding the brakes again. Link to comment Share on other sites More sharing options...
Rexer200 Posted June 14, 2022 Share Posted June 14, 2022 Can you point me to the correct master cylinder on the Caterham shop? There seems to be a few to choose from. Link to comment Share on other sites More sharing options...

Ian Kinder (Bagpuss) - Joint Peak District AO Posted June 22, 2022 Share Posted June 22, 2022 @Hafod I've just fitted the AP item westfield used to supply. Plenty of thread showing on my unions: How are you getting on with yours? Not a lot of room to swing a spanner when fitting them! Link to comment Share on other sites More sharing options...
Hafod Posted June 23, 2022 Share Posted June 23, 2022 No leakage but no threads showing, you have really long unions compared to mine. I’ll post a picture later. Link to comment Share on other sites More sharing options...
Rexer200 Posted July 27, 2022 Share Posted July 27, 2022 Quick question, Does anyone on here have Westfield hispec front of rear calipers and have upgraded from the Westfield master cylinder to the AP racing master cylinder? Any comments on if it’s a worthwhile upgrade considering the £300+ cost? Does it make a big difference even with the HiSpec callipers? Link to comment Share on other sites More sharing options...

I’m trying to find out if it’s worth me upgrading to the Ap racing MC with the HiSpec callipers ? Link to comment Share on other sites More sharing options...
Greenstreak-Andy D Posted August 2, 2022 Share Posted August 2, 2022 I did the upgrade the other way about , swapping out Hi-spec std front for AP calliper and vented disc, rear I went for Golf callipers. I then had a squeal free stoppers and a reliable hand brake. To be fair, I only ran hi-spec for max 200 ish miles, but they did sqeal! Then I went AP m/c Andy Link to comment Share on other sites More sharing options...
BIZZY Posted September 19, 2022 Share Posted September 19, 2022 I have fitted the AP master cylinder from caterham….do I run it now without the fiesta pressure reducer fitted..I am guessing so if it’s now a 60/40 split. Link to comment Share on other sites More sharing options...

The AP cylinder is a 50/50 split, so be careful if using 60/40 as a basis for any calculations! I'm not familiar with the Fiesta part, but if it's already fitted can you run with it and see how it is, before removing it? Link to comment Share on other sites More sharing options...

Absolutely, I've no idea where the 60:40 idea came from, but it's been around for as long as I've been in the club, and I confess to having been one of the guilty ones, repeating it, in the past. It is, as Si said, 50:50. Link to comment Share on other sites More sharing options...
mikey p Posted September 27, 2022 Author Share Posted September 27, 2022 Can anyone confirm the older girlings with P and S outlets are 60/40? I also presume that everyone running the ap tandem MC is doing so with a bias valve fitted? Link to comment Share on other sites More sharing options...

Nope. I'm sure someone possibly is, but 90+% of the installations definitely don't. Link to comment Share on other sites More sharing options...
