Brake fluid? C70 1998

Alright, it's me again. After a couple of threads, I decided to stick with stock rotors and pads for now (they are all due for a change). But anyways, I'm also going to change the lines to the IPD SS brake lines. Now, are there any good "upgraded" brake fluid like Motul Synthetic D.O.T. 4 Brake Fluid (Stillen sells them, can I get these somewhere else for cheaper than $stealin?). The manual states I need 4+ brake fluid. Any recommendations? Thanks in advance.

Humm. For fluid I would go Valvoline synthetic for a street car or a high temp Dot 3 for a track car. Stay away from dot 5. There are better fluids out there then Valvoline but they are upwards of 30 dollars a quart. Valvoline is about 5 and more the adequate for heavy street use.

I've always used ATE "Super Blue" brake fluid in my performance applications. It's compatible with your current fluid but has a higher boiling point.

Re: Brake fluid? C70 1998

I recommend the stainless steel brake lines from SPG9 instead of iPd's.

The reason why is as follows:

Stainless steel lines are superior to the rubber hydraulic lines in every ways except one. Durability. The rubber hydraulic lines are supplied on 99.99999999% of all commercially available cars because of this. Stainless steel lines are recommended to be changed every 2 years. The largest problem is, the stainless steel braiding that wraps around the rubber hydraulic lines allows dirt and sand particles to get in between the fine stainless steel braids. This dirt and sand acts like a grinder on the inner lines. Thus severely decreasing the longevity of the brake lines.

Thus the lines need to be covered in a strong outer covering in order to prevent sand and dirt from being introduced to the braids where abrasion will occur. And I have seen both iPd's and SPG9's in person and have examined both. And it was pretty obvious that the SPG9 stainless steel brake lines had a better covering. However, the SPG9 lines were $25US more for a set of four (2 fronts and 2 rears), or about $125US compared to iPd's $100US stainless steel brake lines.

However, if you will actually follow the recommendations to change the brake lines every 2 years, go with the iPd brake lines. Within a time period of 2 years, the slightly less durable covering on the iPd lines should not become a factor. But if you cannot promise that you will change the brake lines every two years, I'd go with the SPG9, and even then, I wouldn't push it much beyond 2 years.

Just my opinion.
