Hello,

I'm still new to this car, and today I was under the car looking at my fuel leak and trying to figure out where the leak is - I took a look at my front brakes, and I was shocked ! :eek: It looks like the front rotor is not even 10mm thick ! and is a solid rotor.. I didn't look how big the pads or caliper piston is.

So, I thought.. there must be a way to upgrade my brakes, and that there must be a year when they got better brakes. Well.. basically, I want to know whats a easy upgrade for me ? Best bang for my buck ? And if its worth it. Would like links to info or write ups.

I dont know if my rear brakes are working.. stopping power is not great - kinda slow responding, but will stop. Pushing the pedal too hard will nose dive the car and it'll yank to the left. E-brake does not work. All 190's 4 wheel disc ? I see a strange cover inside my right rear wheel like its a cover for my brakes - what is this ? Also I'm wondering if these 15" wheels have the same backspacing so tires can be easily rotated ?

Thanks for any input..

2.5D is a good weight car and suspect the body is about the same with any 190E-2.3-2.6 gas but the engine .Most popular bolt on to up grade brakes for this particular model is reasonable 400E brake ( 1992-1993)system.. with 4 pistons at front and slightly larger two pistons in the rear( ATE ) and you also need of course 400E rotors .Front : 11.6 Inches ( or 294mm x25 Metric) and Rear : 11.inches( or 278mm x24 mm Metric) vented . Shop on Ebay is very reasonable for the $$.
Slow respond on the brakes: Flush your system and check or replace your booster- master/cyl and if you have manual trans also check your slave cylinder too.
DIY brakes is quite easy for one man job ..but when up grade : Ask your mechanik skill first if you're ready for because there will be some mod needed on dust shields ( if you care..)
Result after this(400E) upgrade: Make sure you give the guy behind you a plenty of space...LOL.

Thanks for the input.. I did some searches on the 400e brake upgrade. It sounds like its a good upgrade, but requires 16" wheels. I have the stock 15" wheels and do not really want to change them, unless I can find a set for cheap. I also am ready to buy new tires for my 15" wheels. I found out that 87-93 190's have vented rotors and a larger brake pad, this sounds like a decent setup over my solid rotors. New rotors are cheap and calipers seem to be able to come by cheap on ebay.. like you suggested. So, how will a newer 190 brake setup upgrade do for me ?

There is a few 15" rims suitable for this upgrade like Borbet type "T" and "C" with ET 35 is the best rims for this kinda upgrade( I Had these and just sold it last week). You can have 15" rims with vented rotors only at front but I'd never seen rear vented yet..and your newer setup will be like OEM..:thumbsup:

Thats interesting about the rims.. do you have pics of what those 15" rims you had looked like ? I dont feel that I need rear vented rotors.. I sure am not going to be going very fast in my diesel.. I'd like to have crisp stopping power. You never know when that jerk is gonna cut you off. Lol.

I am pretty sure your front rotors should be vented. Just getting you stock brakes in working order would make a huge improvement. 84-85 had solid front brakes compared to 86-93 (including vented front). The stock system will stop the car very well on the street if it is working well.

Nice calipers.. powder coated ?

I have solid rotors.. they are thin. Maybe there was a overlap in the years they changed to vented.. like a early 86 got solid rotors or something like that.
