1.6 vs 1.8 brakes
Front:
Rear:
About 1" larger in diameter F&R, so around 1/4" all the way around. Front pads have signifigantly larger braking surface, although I dont have them yet to compare, so stay tuned.

can you tell the 1.6 from the 1.8

I typically get comparisons to Jason Lee in person or when I have my goatee.
Prop Valve question... those abs vs non-abs valves... all the same fittings/format? On the hondas, the abs cars use a differently designed valve, ie: its not plug/play. Are they for us?

OK, I'm old and dense and still can't figure out the chart.
Can someone walk me through, let's say, the '94?
They both go up together until they hit about 420?
Then they diverge?
The rear is limited to the straight line pressure from then on up; while the front goes to about 840 while the rear is reaching 600?
When the front reaches 840, is all higher pressure cut off? Front and rear?
I'm confused.

For example, lets say you are applying 1200 (I forget the units of the graph) of total brake pressure then:
a 90-93 the prop valve sends around 700 to the front and 500 to the rear brakes
a in 94-97 car the prop valve would send around 650 to the front and 550 to the rear
a 94-97 abs car the prop valve would still have almost a 50/50 bias

Basically, at low pedal pressures, the hydraulic pressure is evenly distributed between the front and rear brakes, but at higher pressures they skew toward the front brakes at a fixed percentage after a specific knee point. As you can see from the graph, in the earlier 90-93 they start biasing toward the front much earlier than later years.

In fact, as already mentioned some people even just upgrade the stock 1.6 brakes by changing out the prop valve to get less of an aggressive front bias under heavy braking. YMMV.
