You are watching: Why are brake lines coiled at the master cylinder


Coming off the grasp cylinder of every auto I"ve ever before viewed, tbelow are Coils in the line. Why? Body flex? Could the very same function be served with braided stainmuch less hydraulic hose?If I absolutely need to have actually them, have the right to I buy them somewhere? they"d be hell to attempt to make through a tubing bender. The old ones look okay, but once I re mount the brake device, I want all new whatever, so I scrapped the old ones.

It relieves stresses on the lines due to vibrations and also body/framework motions that would stress a solid tough line, you can conveniently remake the coils by wrapping the brand-new line roughly a soup can or simular object. The difficulty through an excessive amount of rubber or braided flexable line is swelling of the line would alleviate braking push. Wright here as signifigant lenghts of functional line would swell alot more than a limited lenght of line. Example watch your rubber lines as someone pumps your brake pedal and watch the flexable line move.

The problem via an excessive amount of rubber or braided flexable line is swelling of the line would reduce braking press. Wbelow as signifigant lenghts of versatile line would swell alot even more than a restricted lenght of line.

If you deserve to actually check out the line swell because of press, you must consider replacing it. I"ve take a pair of vernier caliper via a complete move array on the dial and measured the swell of both good rubber and also teflon lined stainless steel brassist lines. It"s about 1 and a 1/2 thou for either. That was at about 2800 psi.

Years earlier I decided to do an experiment, I develop one brake line through multiple coils, and also one without, both are still functioning 4 years later, however that doesnt expect its not worth it to coil them. If I ever need to relocation the non-coiled one, I"ll coil it bereason its easy and also simple to carry out. No reason not to unless tright here are area constraints. As lengthy as tbelow are a few bends between the mastercylinder and also the mounting point/body/whatever before, it will more than likely be fine.The mastercylinder itself probably moves even more than one would certainly expect.Here is a pic just for referral.
Actually the coiled area of line was designed to cool the brake liquid.Brake performance and also component life will both be diminished via the elimicountry of those coils. Granted, this is measured over the life of the auto and would not normally be noticed by the avarage driver, but throughout repeated difficult braking the brake fluid temperature will certainly rise to a allude wright here it would certainly start to foam and over time would certainly brakedown the seals in the understand cylinder.
Is this write-up your attempt for external validation so that you deserve to feel even more confident about doing something you know will certainly be a mistake in the lengthy run?
If you have the right to actually watch the line swell bereason of press, you must think about replacing it. I"ve take a pair of vernier caliper via a complete sweep variety on the dial and measured the swell of both great rubber and teflon lined stainmuch less steel brassist lines.

Even a brand also brand-new rubber/functional line will certainly flex when the pedal is pushed I speak to this motion as a result of swelling not a bubble or rupture in the line. As also declared the MC will also move as it is bolted to the booster as the pedal is pumelted.

I taken you the initially time, however offered that a lot of systems operate at about 14-1500 psi and I"ve tested both forms of lines with a gauge at the end that hit 2800 psi, I don"t think your original statement of losing push as a result of line swell is valid unless I started with a lot more than 2800 which I doubt. Especially since the measured swell is much less than 2 countless an inch. It would certainly need to balloon considerably and store ballooning for there to be a push loss of any significance.
Really? I"d prefer to watch documentation on that one. Seems to me the coils would be beside the wheel cylinders/calipers for cooling. The grasp cylinder doesn"t make a lot warmth however it does move roughly some. :shaking:
The handle to my floorjack functioned excellent for me. http://www.14kft.com/images/Play/VancoHydroboost/DSC01145w.jpg
It is simpler than you"d expect to make the coils...Just wrap the tubing approximately a cylinder prefer j5 did. You don"t need to dick with a tubing bender.

Really? I"d prefer to watch documentation on that one. Seems to me the coils would certainly be next to the wheel cylinders/calipers for cooling. The master cylinder doesn"t make a lot warmth yet it does move around some. :shaking:
I understood you the first time, yet given that a lot of devices run at approximately 14-1500 psi and also I"ve tested both kinds of lines via a gauge at the end that hit 2800 psi, I don"t think your original statement of losing push as a result of line swell is valid unmuch less I started through a lot more than 2800 which I doubt. Especially since the measured swell is less than 2 thousands of an inch. It would need to balloon considerably and store ballooning for tbelow to be a push loss of any kind of significance.

I"m going with vibration or activity regulate.Even a small activity over time *could* cause metal tiredness and also potentially a catastrophic faiattract.
It will certainly work and also will certainly work great, they are mainly for show and not go. In excessive applications it isnt ideal however once do we execute what is ideal?

No, there"s not. Maybe for rubber flex lines, however for top quality stainless steel sheathed lines, it functions without troubles... and with a much more positive "feel" to the pedal than a stock setup of steel and also rubber lines.Randii

I disagree. I have actually had a few customers perform this over the years and the majority of are dissatisfied until they perform it appropriate. Btw, my agency sells stainmuch less hose and also not tough line. Use the abolute minimum flex line required. I choose the vehicles that have actually hard line on the web links btw.Also regarding the street rod comment, I have thrust a number of street rods with high dollar brake devices. They for the many component suck.
