Don’t over look the lifespan of your Brake Fluid
Brake fluid has a fairly spot of responsibility put upon it, doesn ’ metric ton it ? When we step on the anchors, we rely on it to do the necessity work under coerce and bring things safely to a stop. Yet, like most other car components, it has a finite life and shouldn ’ metric ton be overlooked as an substantive element of a routine sustenance schedule .
Brake Fluid absorbs moisture
The problem is, despite its complexity, brake fluid is hygroscopic – in other words, it absorbs moisture that permeates through the rubberize hoses, seals, and via respective fittings. a soon as moisture has been absorbed, the fluid becomes less efficient at its job. not only that, but the moisture can corrode the brake arrangement ’ sulfur internals, causing caliper pistons and wheel cylinders to seize and metal brake pipes to rust from the at heart knocked out. This is why it ‘s thus important that brake fluid should be replaced every two years .
Which brake fluid do I need?
All brake fluids must comply with north american english DOT specification and most cars use either DOT 3 or DOT 4 diol ether-based types. The latter has a slightly higher boiling point and is said to absorb less water, so it is much seen as an upgrade for cars that were originally designed to use DOT 3. Both are compatible, so you can mix them together if you should therefore wish. We stock DOT 4 brake fluid for Porsche and VW vehicles.

What do the Brake Fluid DOT numbers mean?
On top of DOT 3 and DOT 4 there are a couple more, but be careful with them. Let ‘s jump to DOT 5.1. It has an tied higher boiling point than DOT 4, but it is well more expensive to buy and generally alone used on contest and high-performance cars. queerly DOT 5 is a different animal ! DOT 5 is a silicon-based fluid, which means you can ’ metric ton mix it with other brake fluids. It has a 500F boiling point, fair like DOT 5.1, but with its silicon base it is n’t hygroscopic and it wo n’t strip your paint off if you spill it. It is considered to be slenderly more compressible, which could cause issues if your vehicle has ABS and Traction Control. Incidentally, don ’ thyroxine pay any more for brake fluids that shout about being ‘ celluloid ’ – they ’ re all synthetic .
How can I tell my brake fluid needs changing?
fresh brake fluid is a light straw color, but as it becomes contaminated with body of water or debris from failing inner seals, it becomes much dark. As moisture is absorbed, the fluid ’ s boiling point becomes lower. There are specialist devices to assess a bracken fluid ’ s boiling detail, but they ’ re expensive, and only bigger garages are probable to have them. Either way, adhering to the biennial regimen and flushing the solid system through with fresh, new fluid is constantly the best, most fail-safe method of ensuring it ’ mho still able to do its job properly. Some brake fluid reservoirs have a trickle that traps debris, so form sure it ’ mho clean before changing your fluid. Don ’ t forget that brake fluid will strip paint in seconds so be super careful to avoid any drips.

How do I change my brake fluid?
Unlike renewing the locomotive oil on your car, brake fluid is changed by draining the old fluid knocked out at the bottom, while the new fluid is poured in at the top. Because it is a hydraulic fluid, it is vitally significant that no air travel gets into the organ pipe, therefore the want to bleed the brakes of any air. In short, bleeding your brakes is done like this. Starting with the brake caliper or wheel cylinder furthest away from the brake master cylinder, and connecting a pipe onto the run nipple, and then dropping that clear shriek into a container of newly brake fluent. Ensuring the reservoir never runs dry ( as it will let atmosphere in ), open the run nipple, and then pump the brake pedal. This pump will draw new fluid into the system, and push the old fluid and any vent in the system out. At the point the bicycle becomes firm, and the fluent runs out clear, move onto the adjacent corner, and repeat.
Bleeding brakes on your own
You can besides buy a ‘ one-man ’ kit that features a one-way valve in the pipe which makes life sentence easier if you can ’ thyroxine find an assistant ; we offer a version by Gunson ’ s called the Eezibleed brake bleeding kit here. Another method that enables you to bleed the brakes on your own is to use a supercharge bleed kit, powered by compress tune from a car tire. These purportedly reduce the hazard of damaging the maestro cylinder seal, which can happen when the brake pedal is in full depressed . Another choice, rather of pressure bleed brakes, is to vacuum bleed them alternatively. The principle is just the lapp, but rather of pushing fluid through the system, you draw it out using a hand-held pump. The old methods much work out simple and cheaper though ! I hope this aid .
