Rear brake line

hi guys n girls took my car out Friday when suddenly brake pedal to the floor. After nursing her home jacked her up yesterday and found brake fluid dripping from around the front end of gearbox. I'm guessing the pipe over the transmission has failed. My question is are these able to renewed with the engine in situ.

Hi Simon Promax do a flexible braided one, may be worth a phone call for further info. see below. http://promaxmotorsport.co.uk/products/2003-braided-brake-hose-996-models-for-over-transmission.aspx Good luck Andy

Thanks Andy will have a look into it. Hope you and the family well.

Dovehouse replaced mine with braided hoses without dropping the gearbox. The hoses were more expensive than oem, but the Labour was much less than.

Hi Andy quick update I purchased the braided pipe. What a great idea took the old one out and screwed the braided pipe to it and pulled ove the trans with no problem at. Did unclimbed the old one first. Just got to bleed it now thanks for the info on the pipe mate such a straight forward job as well. One happy bunny.

Hi Simon And thanks for the feedback, glad to know it did the job. Andy

all, ProMax has stopped trading and cannot provide me with the spec of this brake line. Has anyone got it or have one they can measure? I need the length and end fittings types primarily so I can have one made up? Or provide an alternative supplier? Thanks in anticipation, Garry.

Hi Gary I've just purchased one last week and fitted with ease. I can only measure the length of the old hard line which I still have the fittings are just as standard

Thanks Pieman7, I had ordered it but they refunded, it would be easy to have one made if I knew the spec. If you can measure the hard line so that I have a reference when I look at mine. Cheers Garry

Hi Garry, Simon & All. It seems Promax Motorsport have now closed down apart from selling there existing stock, (according to their answer phone message) I have left a message asking them if they can give me the name of the suppliers and sizes for this part and if they get back to me I will let you know. Failing this there are a few sites who will custom make them, It would be good to know the length though. I don’t know if Simon has that answer ? Meanwhile if anyone has any luck sourcing from elsewhere please can you please let me know for future info for members. Kind regards Andy

Hi guys apologies for the late reply straightened my old rear pipe line and it measures 2850mm both ends have male threads one end is the normal size that screws into the upgraded braid hoses we fit to the callipers. The other end is slightly larger I'm sure your local dealer service guys could help out knowing the exact sizes. The flexible line I bought had the same size both ends but they then used adapters to both ends.

Thanks Pieman7, I'm guessing that the length is OK with a flexible line and is not that important to get perfectly accurate. Does it replace the whole line from back to front or just over the gearbox, at nearly 3 metres I assume its to the front (i.e. the whole line)? Another option would be to put a hard line in from front to back and join to a flexible over the gearbox only? Thanks Garry

Hi Garry This is the route of the offending pipe courtesy of Simons facebook post.

thanks Andy, Can you post the pic without the black line drawn on please. Do you know what the fitting size is on the end that goes into the block, is it standard M10x1.0 male? Thanks Garry

Garry I'm not sure of fitting size perhaps Simon can answer that photo of block

Hi, I was looking through this thread and I'm interested to know a bit more about the braided brake hose line you had done over the engine as i also need this on my 996. I'm based in Bristol so not really an option to use Dovehouse but any info you have re parts would be really helpful to give my Indy (Advanced Car Care) Thanks in advance. Darren

Hi Darren, I did this a couple of years ago and had the brake line made up. I remember the fittings were a bit difficult to get right, but I will look through my notes and let you know what I bought. Used the old brake pipe to tie the new pipe to. Cheers Garry

Thanks Garry that is really good of you. Look forward to hearing back. Cheers, Darren

Hi Darren, I did it in 2017, got the pipe from Promax motorsport, was £63 incl delivery, but suspect they have gone out of business. You can get it made I believe the length and fittings is detailed in this thread http://www.promaxmotorsport.co.uk/ Cheers garry

Hi Garry, Andy kindly gave me contact details for both BRT Motorsport and Earl's Performance Products for braided Hose pipes. BRT have responded and they are looking in to the length and fittings i need for going over the engine from the O/S rear flexi so I will update on here once they confirm. Earl's have yet to respond so i will chase them up. I note the length for back to front has been posted on this thread @2850mm but not for over the engine so if anyone knows the length and fittings, please post. Thanks D

Darren I thought that length from Simon was for the over engine route, surrgest you PM Simon to. Confirm. Andy

Hi Andy, Yes, i've re-read and my mistake it does look like the length in question is over the engine but i will PM Simon to check Thx D

Pretty sure that was the over engine length when I did mine. Cant confirm though. Regards Garry

Hello all, found this post after searching as my rear brake pipe has sprung a leak. While I’m in there I’m going to replace both rear lines and have contacted a couple of companies as mentioned in this thread. BRT seem to be the most on the ball and can supply the hose(s), but they need confirmation of the connector sizes. I believe one end is M10 and possibly M12 the other but am unsure. would anyone be able to help? thanks tim

Hi there, when you say rear brake pipe, do you mean the flexis, or the hard line? If it's the hard line, which can suffer terribly from corrosion underneath and around the plastic retaining clips, then depending how bad and how high up it is, it can mean full engine out to replace it! Great design Stuttgart, thank you! Once out of course, you'd be silly not to address IMS/RMS/ oil separators/clutch etc...(unless you were already very confident in these consumables), so you can end up with quite a bill for what started out as something that you might have thought of as being no big deal. Some competent indie shops will do a good job of splicing in a section and a union using copper nickel pipe that can be fabricated to fit down to where the flexis start. Just sharing some recent experience. Good luck all.

Hi, I recently had my over-gearbox brake hardline replaced with a flexi at my local specialist, they were able to source a braided hose (of the right length and with the right fittings) to replace the hardline from RPM Technic

Hi Skate99, I’d be interested to know where you sourced the flexible hose for this job (or who your specialist is) as I need this doing as well but trying to avoid the 12hours labour I’ve been quoted. I’ve seen "Rocket Dog” appear to offer not only a braided flexi kit but a full brake pipe kit can anyone confirm or has used this at all? Thx

Hi Sully3608, RPM Technic supplied the part and Wrightune fitted it, hope that helps!
