## Overview

The PTE Brake Fluid Tester is a compact, pen-shaped device calibrated exclusively for DOT 4 brake fluids, widely used in vehicles since 2006. It quickly detects moisture contamination via LED indicators, delivering results in seconds to help prevent brake failure. Powered by an included AAA battery and featuring automatic shutoff, it offers a fast, reliable, and user-friendly way to maintain brake system safety.

## Description

Staying safe and knowing that your car is in top condition is most important. Ideally, brake fluid should be checked regularly and changed every one to two years. As moisture seeps into the brake system through the brake hoses and seals the brake fluid will become contaminated and the danger of brake failure will increase. This pen-shaped brake fluid tester can easily help determine whether it's time for you to change your brake fluid. What to do: 1. Turn on the brake fluid tester by pressing the button. A green light should light up. If the light does not come on, it may be time to change a battery. 2. Unscrew the lid for the brake fluid reservoir, and take off the cap for the brake fluid tester. 3. Dip the test probes into the brake fluid and the LED lights will indicate the percentage of water in the brake fluid. 4. After testing, remember to screw the lid of the brake fluid reservoir back on tightly. 5. The tester will automatically power off after 12 seconds of inactivity. The LED lights will indicate the percentage of water in the brake fluid: Green: None Green/Yellow: Less than 1% Green /Yellow/Yellow: Approx. 2% Green/Yellow/Yellow/Red: Approx. 3% (Time to change brake fluid.) Green/Yellow/Yellow/Red/Red: Approx. 4% (Change brake fluid immediately). Please note:- This brake fluid tester is calibrated for DOT 4 brake fluid only, which is used in most cars produced since 2006. - Replace the battery if the green LED light no longer lights up after you press the button. - Wash the test probe with tap water after every use. - In case of skin contact with brake fluid, thoroughly wash the affected skin or clothing with water. - Do not expose brake fluid to the atmosphere for a long time as it is highly hygroscopic.

## Features

- Quick and easy way to test for moisture content in the brake fluid; results appear in seconds
- LED light indicators show percentage of water in the brake fluid
- Calibrated for cars using DOT 4 brake fluid only (found in most cars produced since 2006)
- Takes 1 x AAA/1.5V battery (included)
- Only takes seconds to know the results

    A quick and easy to use tester that takes the guesswork out of determining the condition of your brake fluid.
  

*by S***T on Reviewed in the United States 🇺🇸 on February 9, 2016*

I purchased this brake fluid tester after comparing several types of testers on the market.  Price can range from less than $10 for test strips to over $150 for a professional test kit.I live in the Pensacola Florida area, and the high humidity greatly impacts the life of brake fluid due to the hygroscopic nature of DOT3, DOT4 and DOT5.1 bake fluids (this is specifically a DOT4 fluid tester).  In the past, I resorted to changing out the fluid every 12-18 months in order to combat the negative effects of high humidity.  This interval essentially ensured the fluid was not water saturated, but the effort (especially on my Honda S2000) tended to be time consuming and messy, even when using a positive pressure bleeder.  This repetitive cycle based on an educated guess was too ambiguous, and the sense of not knowing the actual condition of the fluid eventually drove me to invest in a fluid tester to dictate the appropriate time to change fluid based on the actual condition of the fluid, not by a relatively arbitrary time interval based on an educated guess.I personally use ATE TYP200 fluid, which is currently the best DOT4 fluid readily available - for the broadest range of applications.  I found through years of use that ATE TYP200 lasted longer than any of the other fluids I have used, and covered conditions ranging from light track use, severe hot weather use and in cold winter conditions.  I've used TYP200 in ambient temperature ranges from -25F in Oklahoma to 129F in Bahrain with reliable, consistent and durable results.I do not have professional brake fluid testing equipment, but I decided to sample a variety of brake fluids covering the spectrum of new to neglected, to see how well the tester would measure the differences between samples.  The first fluid I sampled was my S2000's fluid.  It has been 18 months since the last brake fluid change in my S2000, and this tester showed the fluid had approximately 1% water saturation, which is still reliably serviceable.  I then tested unused fluid that has been stored in a pressurized container for 18 months and it tested at 0% saturation (which is what you would expect).  I then tested my neighbor's car, which hasn't had the fluid changed in ever 3 years and it showed 4% saturation.  I then shamed him into taking it to the dealer to have the system flushed with fresh fluid.  Given these results I was confident the tester was actually measuring what the manufacture claims it should.With regard to determining when you should change your brake fluid, I would say it depends on the type of car and the type of brakes the car is equipped with to determine the acceptable saturation level.  My threshold for my S2000 is 2% saturation due to the fact the car is equipped with custom forged aluminum calipers - and I'm not willing to run the chance of internal corrosion damaging the brakes.  2% saturation limit also ensures the brake fluid will still provide the highest level performance in both street and track conditions.  I believe 2% saturation in my daily driver (and in any standard street car) is acceptable for continued use.  A 2% saturation level provides a comfortable threshold of performance, but also provides a good benchmark for a maintenance reminder; putting you on notice that the brake fluid will need servicing within a 3-6 month window.  A saturation level of 3% is not acceptable for extended use (even though this tester shows 3% in the 'caution' range), and the brake fluid will begin to show degraded performance at this level (you're solidly in the wet boiling point temperature range at this point).  Fluid discoloration is also an important measure of fluid condition, but water saturation can occur before the fluid turns dark.I believe this tester provides a simple, relatively accurate and easy to distinguish measure of the water saturation level of your car's brake fluid.  This can provide piece of mind knowing that your fluid is still serviceable, that you need to start planning to service your brake fluid, or a fast indication you need to flush the system to ensure reliable operation and longevity of your brake system.  I believe the tester is priced reasonably, but there are a few improvements that would bring it to 5 stars.There are a few reasons I only rated this tester at 4 stars.  First, the cheap 4 LED 'display' belongs back in the 1980s and adds to this tester's cheap appearance and feel.  A simple LCD display (similar to the one used on the ZeroWater TDS meter) would provide a much more accurate presentation of information.  Even if the LCD presented information in 0.5% increments, the information would be twice as resolved as what the meter currently shows.  Secondly, this tester could provide more than one "calibration" setting and could be designed to provide saturation levels for DOT3, 4 and 5.1 fluids.  The switch between calibration settings could be done with a simple press of a button, and the calibration designated on the LCD display. Lastly, this tester is made with very cheap materials and the fitment of the parts is not very good.  Subsequently, the battery door is extremely hard to open (required prying).I think it goes without saying most customers would be willing to pay $5-$10 more for a better built tester with the mentioned options - and, it would earn a 5 star rating.

This started when my dealer said “Hey! You need bring in your car for an oil change and to flush the brake fluid.” NOTE: my car is still under warranty, which includes all service; so I brought my car in because it was something I did not have to do myself this time. Anyway, I am also one of those people who does most of the service when I can. I admit, I am kind of old school and never flush the brake fluid out unless it’s dirty or smells bad. With that said, I came across this nifty gadget. Basically, you turn it on and dip the leads into the brake fluid and it immediately provides a break fluid reading. It lets you know the condition of your brake fluid – if it needs to be changed or not. Obviously, this brake fluid tester provides a more accurate reading than looks or smell, and for the $7 you cant beat this tester that simply works.If your one of those people who does not work on your own car and you have to rely upon someone being honest, this is a good idea for you too. It really is simply to use. Like I said, unscrew your brake fluid reservoir (which is under the hood), turn the tester on, and dip it into the fluid; you will have an instant reading and know if you have been provides honest information. Keep in mind that many vehicle manufactures are putting brake fluid on routine maintenance every two years of so.
