Just changed the brake and clutch fluid on Civic, Jazz will be next to get done. Use a MityVac and makes the job a doddle, jacking up car and getting the wheels off is the hardest part. It helps if clean around nipple and take it out and put a couple of wraps of plumbers teflon tape on the thread nearest hexagon, then it sucks fluid and not foam due to air getting around the thread. Last time I did brake bleeding I found some thick 'O' rings that were a tight fit on nipple thread and they did the job of stopping air, but the brake fluid attacks then and they crumble away before you can get the benefit of them next time.
There are two types of DOT 4 standard and ESP, the ESP is designed for use in vehicles with Electronic Stability Program and from what I can gather is a higher quality / lower viscosity fluid than standard DOT3 / 4. Just to muddy the water some brake fluid makers label their fluid 'synthetic' but as they are based of Glycol Esters they are all synthetic ( ie. man made and not naturally occurring ). For some reason DOT 5 is silicone based but DOT 5.1 is glycol based - confusing or what, the main difference between DOT 3, 4 and DOT 5.1 is the boiling point.
Anyway, because the Civic and MK2 -> Jazz have VSA ( Honda Version of ESP but labelled Vehicle Stability Assist ) which can selectively apply the brakes on each wheel to stabilise the car during a skid I used the DOT 4 ESP brake fluid ( Mobil ) - the ESP fluid is supposed to make the ESP / VSA more effective - but the Jazz Handbook makes no mention of it, just says DOT 3 or 4 fluid. ESP fluid is only a couple of £'s more expensive which over 3 years is not a lot.
Is ESP label just for marketing. like the 'synthetic' labeling
If it had been twice the price may have thought about it, but £9.50 instead of £7.50 for 500ml is hardy a deal breaker.
