qkingston Posted May 19, 2019 Report Share Posted May 19, 2019 So I've fitted all the brake lines on the rolling chassis and I would quite like to test the system before I put the body on; new brake lines, piston seals etc so chance of a system leak is possible. Has anyone done this before putting the body on, so obviously no master cylinder/brake pedal etc. Has anyone devised a tool which can pump in brake fluid then lock in the pressure to do a drop test? Much appreciated David Quote Link to post Share on other sites
ctc77965o Posted May 20, 2019 Report Share Posted May 20, 2019 Honestly it seems a little OTT to try to test this system before it's fully assembled...I dunno how long it's gonna take you to put the rest of the car together but I would imagine that the brake lines being wet with fluid will create its own problems. But if you really wanna do it you'll need a grease gun or other hydraulic pump plus a t piece with a 3000psi gauge... Pump the fluid through, bleed everything then pump it up to 2000psi and leave it 30 mins. Quote Link to post Share on other sites
Andy Moltu Posted May 20, 2019 Report Share Posted May 20, 2019 You will have to take it apart anyway if only to refit the master cylinder and the brake lines that run in the engine bay. In the end it's probably not a good use of time. Quote Link to post Share on other sites
Waldi Posted May 20, 2019 Report Share Posted May 20, 2019 +1 For the above reasons I waited with filling and bleeding until the body was installed. I used silicone brake fluid, so no concerns with damaging the paint. Waldi Quote Link to post Share on other sites
