GS 300/430 brake pipes.

[Delp]

Hi all looking to buy a GS 300/430 MK 2 really prefer the 430. Anyway I've seen one I like, but far from me. And the only issue it's got is the brake pipes call corroded on the MOT. So I guess at some point it's got to be done. Is this a major job and how much would it cost, any advice be Helpfull.🙂

I'm surprised no one has got back to you on this.  Unless someone on this forum has done GS brake lines and gets back to you, it may be worth checking with a brake specialist who makes their own as genuine parts (like most things Lexus) won't be cheap.  Good luck with it, I really like the MK2 GS, especially the 430 which I believe does 0-60 in something like 6 seconds!

The brake pipes on the GS are plastic coated except for the last inch or so in the wheel arch where they join to the flexible hoses. It is this short section that rusts. 

To replace the rear sections Lexus will quote £1200+ because to get at them the rear subframe has to come off along with all the under panels. Your local garage can cut off the rusted sections, and replace with extension pieces for very little money.

Hi guys thankx for the replies.  So the bit that's rusts is the last section that joins to flexi pipes. So you wouldn't need to replace all the lines as that's a 'Biggy'. So worst case scenario is if the plastic side goes then it's an issue. John is this something you have had done.🙂

I have done this on many occasions "not on a GS", but the basics are followed by many car manufactures. If you have a brake pipe flaring tool "around £20", and fittings it is something you can do yourself. Many motor factors, and parts shops have the equipment to make up brake pipes to order, but you need to be able to put new nuts, and flare the pipe ends that are on the car when you cut off the rusty section.

Again you can replace the whole length of pipe if you wish taking an easier route than the original pipe as this was fitted on the underside of the body shell before such things as exhausts, sub frames, and under body covers. The OEM pipes can be bought ready shaped from Lexus at around £85 for the rears, but it would take many hours to remove eveything that is in the way for fitting them.

Similar here, mine had corroded rear axle pipes so my local garage did them for around 40.00.

Like Britprius, I’ve not done pipes on the GS, but have replaced all brake lines on my Corrado. It is a lot easier to do than you might think, albeit they may not look quite as good as the factory pre-shaped ones. I’d always recommend the kunifer cupro nickel pipe, rather than standard copper, much more corrosion resistant.
