2soops Posted August 11, 2012 Share Posted August 11, 2012 Was hoping someone may be able to help and provide a part number for a brake master cylinder. My car started as a Jspec TT Auto, but is now a 6spd Manual. I am about to upgrade to UK brakes, and read on here the upgrade often leaves a spongy feeling brake pedal. I assume this is because of the extra pistons in the Uk set up, and slightly more fluid being required to push them out. I spoke to Toyota earlier about whether the UK brakes had a larger master cylinder for the extra pistons, and they confirmed there are 4 different part numbers for varying sizes/models/years. They couldn't however tell me which was the largest internal diameter. Does anyone on here know a part number for the larger spec master cylinder so i can get one ordered, my car also has abs if that makes a difference. Thanks for any help Al Quote Link to comment Share on other sites More sharing options...
