billybluesky 1 Posted April 5, 2010 Hi maybe someone could give some suggestions. After fitting 1.9 calipers to my 1.6 the pedal would go the floor, so after 23mm master cylinder, goodrich braided hoses all round, and new fluid result normal braking, but you still cant lock them up if you stand on them! would mintex ds or ferrodo 1144`s really make that much difference for fast road use?

Anthony 1,002 Posted April 5, 2010 Something sounds amiss to me, as it should lock up easily enough even on standard pads - you did check that the sliders move freely on the calipers? Share this post Link to post Share on other sites
Tom Fenton 1,536 Posted April 5, 2010 Some of the cheaper pads are just crap though to put it bluntly! Try some decent brand (Mintex, Ferodo) standard pads and see if that helps matters? I had some APEC pads in my 205 for a month before removing them as they were awful. Share this post Link to post Share on other sites
billybluesky 1 Posted April 5, 2010 Stripped, freed,cleaned and painted the callipers before fitting, the pads that are in are pretty standard partco/unipart type. Share this post Link to post Share on other sites
matt.f 16 Posted April 6, 2010 If fitting 1.9 calipers to a 1.6 do you need to change the master cylinder or anything else?or can you just swap caliper for caliper? Share this post Link to post Share on other sites
Fox 3 Posted April 6, 2010 I swapped just the calipers and all was fine, I hardly even noticed any difference. I'd imagine you've still got air in there somewhere Share this post Link to post Share on other sites
pug_ham 243 3 Cars Posted April 6, 2010 Someting isn't right but why have you fitted a 23mm mc with standard brakes? Un-necessary overkill imo. If fitting 1.9 calipers to a 1.6 do you need to change the master cylinder or anything else?or can you just swap caliper for caliper? Straight swap over, caliper to caliper but you might need to untangle the flexi when the hose is tightened into the caliper. Graham. Share this post Link to post Share on other sites

Sorry i did`nt put that first i fitted the calipers (my daughter bought for me from the for sale section), which was advertised as mi 16 brakes, which made the pedal travel literally to the floor hence the 406 m/c, i didn`t measure the piston i assumed they were just 1.9. Any ideas? Share this post Link to post Share on other sites
Tom Fenton 1,536 Posted April 6, 2010 Hmm, it could be that they are not 1900 calipers and that is the problem. I have a couple of sets of 1900 calipers, yours for a special price if you want them, PM me. Share this post Link to post Share on other sites
kyepan 291 Posted April 6, 2010 (edited) hang on, am i being stupid or would 1.9 calipers have a different and incorrect offset when used on 1.6' hubs and discs.... hence the issues? Edited April 6, 2010 by kyepan Share this post Link to post Share on other sites
pug_ham 243 3 Cars Posted April 6, 2010 Have a look on the caliper body, iirc there ought to be a number stamped on it somewhere above the piston for the size. I've got some somewhere I'll have a look at but I think Mi16 calipers had a 54mm piston not 48mm like both the 1.6 Bendix & 1.9 Girling calipers. Mi16 brakes (calipers & yokes) don't fit the 205 GTI on any mixture of hubs though afaik. What size discs were you using wioth them because the Mi16 takles 266mm discs? hang on, am i being stupid or would 1.9 calipers have a different and incorrect offset when used on 1.6' hubs and discs.... hence the issues? No, 1.9 calipers & yokes fit onto the 1.6 hubs for use with the 1.6 discs etc (I have them on my car) but you can't mix the discs between 1.6 & 1.9 hubs. Graham.

matt.f 16 Posted April 7, 2010 And you need longer caliper bolts iirc Share this post Link to post Share on other sites
Tom Fenton 1,536 Posted April 7, 2010 Shorter caliper bolts for the 1900 Girling calipers, longer bolts for the 1600 bendix calipers. Share this post Link to post Share on other sites

I`ll take a look at the weekend weather pemitting, and i`m using them on standard 1.6 discs. I seem to remember one of them having lucas stamped on it, and thinking it must be a later replacement Bill Share this post Link to post Share on other sites
