   I bought this type 3/4 synthentic brake fluid for a few upcoming brake jobs as I plan to change pads and totally bleed out the old fluid and replace with this product. Price value was good for this 32 oz bottle

   My only beef and the reason why I am not giving it 5 stars is truth in advertising. The image of the product clearly shows that this is “Dot 4” brake fluid. The bottle arrived and it has a different label which indicates “Dot 3/4” brake fluid. Now, there might not be a difference, but I feel the label of the product you receive should match what is sold. However, the brake fluid went into the car properly and it stops. So it performs as it should. If the 470 degree boiling point is right, then awesome.

   Great for use in many cars. Easy to pour and appears to be high quality.Will be used for brake flushes in both imports and American cars.

   I like that it comes in a 1 gal quantity because I had a full system to flush and bleed. Also, I have noticed some reviewers complain that they were cheated because the label says “DOT 3+4” and they think this means that the product is a mixture of DOT 3 and DOT 4. This is mistaken. The difference between DOT3 and DOT4 is the 4 has a slightly higher boiling point which will help resist heat fade. However, the DOT 4 often comes labeled as 3+4 because the two are cross compatible, meaning that if you have a brake system that takes DOT3, it’s OK to put DOT4 into it, and it’s OK to add DOT 4 to the system as a top off. Now when it comes to DOT 5, that is a silicone fluid that is not cross compatible and should never be added to a DOT 3 or DOT 4 system. So the DOT 3+4 product is actually the DOT4 spec, it is not a blend. If you want the full DOT4 boiling point then you must totally flush your system with all DOT 4, and if you add DOT4 to a quantity of DOT3 fluid you won’t get the full boiling point but the compatibility is OK.
